Zhang, Jialong; Mason, Alexander H.; Motta, Alessandro; Cesar, Laryssa G.; Kratish, Yosi; Lohr, Tracy L.; Miller, Jeffrey T.; Gao, Yanshan; Marks, Tobin J. published an article in 2021. The article was titled 《Surface vs Homogeneous Organo-Hafnium Catalyst Ion-Pairing and Ligand Effects on Ethylene Homo- and Copolymerizations》, and you may find the article in ACS Catalysis.Formula: C9H11Br The information in the text is summarized as follows:

Heterogeneous catalysts have long dominated polyethylene and polypropylene production, but understanding their catalysis is challenged by uncertainties in active site structures and percentages. Surface-bound organometallic catalysts are an emerging strategy to combine successful homogeneous catalysts having well-understood structures, relatively high percentages of active sites, and exceptional control of selectivity, with the attractions of surface catalysts, to transition promising homogeneous systems to large-scale heterogeneous ones. Nevertheless, surface-bound olefin polymerization catalysts typically produce ultrahigh Mw’s but with low activity and comonomer selectivity. Here, the authors report the systematic synthesis and characterization of pyridylamido-Hf complexes and their corresponding surface catalysts chemisorbed on sulfated alumina (AlS) and zirconia (ZrS). Comparative ethylene homo- and 1-octene copolymerizations reveal similar activity and 1-octene selectivity trends in the homogeneous and heterogeneous systems. For the surface pyridylamido-Hf catalyst series, large variations in activity (up to 10x) and 1-octene incorporation (up to 28x) are achieved by ligand and support manipulation. While the homogeneous catalysts exhibit pos. comonomer effects in ethylene/1-octene copolymerization, the surface catalysts behave oppositely. Extended x-ray absorption fine structure (EXAFS) reveals significantly elongated Hf···O bond distances vs. typical Hf-O covalent bonds (2.06 vs. 1.97 Å). D. functional theory (DFT) anal. of the heterolytic ion pair separation enthalpies, olefin insertion energetics, and NBO/Bader charges also suggest electrostatic Hf cation-anionic support binding and catalytic patterns, which are modulated by the ion-pairing energetics and ligand architecture. The results came from multiple reactions, including the reaction of 1-Bromo-2-isopropylbenzene(cas: 7073-94-1Formula: C9H11Br)

1-Bromo-2-isopropylbenzene(cas: 7073-94-1) belongs to organobromine compounds.Depending on the type of carbon to which the bromine is bonded, organic bromide could be alkyl, alkenyl, alkynyl, or aryl. Formula: C9H11Br Alkyl bromides are mainly used as alkylating agents and also find application as a solvent to extract oil from seeds and wool.

The article was written by Paradiso, Veronica; Menta, Sergio; Pierini, Marco; Della Sala, Giorgio; Ciogli, Alessia; Grisi, Fabia. The article contains the following contents:

In order to design improved chiral ruthenium catalysts for asym. olefin metathesis, enantiomeric catalysts incorporating C1-sym. N-Heterocyclic carbenes (NHC) ligands with syn-related substituents on the backbone were synthesized starting from meso-1,2-diphenylethylenediamine. The absolute configuration of the enantiomers of the desymmetrized meso diamine was assigned by optical rotation anal. and in silico calculations, and was found to be maintained in their resp. ruthenium catalysts by comparison of the relative electronic CD (ECD) spectra. The catalytic behavior of the enantiomeric ruthenium complexes was investigated in model asym. metathesis transformations and compared to that of analogus complexes bearing C1-sym. NHC ligands with an anti backbone. Modest enantioselectivities were registered and different catalyst properties depending on the nature of stereochem. relationship of substituents on the backbone were observed After reading the article, we found that the author used 1-Bromo-2-isopropylbenzene(cas: 7073-94-1Recommanded Product: 1-Bromo-2-isopropylbenzene)

The title of the article was 《Construction of Axially Chiral Indoles by Cycloaddition-Isomerization via Atroposelective Phosphoric Acid and Silver Sequential Catalysis》.Category: bromides-buliding-blocks The author mentioned the following in the article:

Herein, the atroposelective organo/metal combined dual catalysis strategy for de novo construction of valuable axially chiral indole frameworks I [R = n-Bu, Ph, 2-naphthyl, etc.; R1 = H, 6-Br, 7-C6H5, etc.; R2 = i-Pr, t-Bu, cyclohexyl; R3 = Boc, Cbz] was developed. This protocol utilized a catalyst system of two chiral phosphoric acids (1 mol %) in combination with AgNO3 (1 mol %) and was based on the unreported intermol. cycloaddition-isomerization reaction of recently introduced C-alkynyl N,O-acetals and 2-naphthylamines. An important class of hitherto inaccessible axially chiral indoles with a C-N axis were obtained in good yields and enantioselectivities. The axially chiral indoles obtained also provided a platform for the catalyst-controlled atroposelective synthesis of axially chiral indoles bearing two C-N axes, which were difficult to access by the existing methods. This work was also an example of 2-naphthylamines used as 1,3-dinucleophiles and three-atom (CCN) synthons in cycloadditions1-Bromo-2-isopropylbenzene(cas: 7073-94-1Category: bromides-buliding-blocks) was used in this study.

Application In Synthesis of 1-Bromo-2-isopropylbenzeneIn 2016 ,《Synthesis of Conformationally Constrained Esters and Amines by Pd-Catalyzed α-Arylation of Hindered Substrates》 was published in ACS Catalysis. The article was written by Martin, Anthony; Vors, Jean-Pierre; Baudoin, Olivier. The article contains the following contents:

The α-arylation of sterically hindered silyl ketene acetals (SKAs) with sterically hindered aryl bromides occurs efficiently using Pd[P(t-Bu)3]2 as the optimal catalyst and ZnF2 as a promoter. Less sensitive P(t-Bu)3-based catalysts could be also employed but showed a lower activity. The reaction showed a broad scope with regard to both coupling partners, including heteroaryl bromides and cyclic SKAs. It also proved to be scalable to multigram quantities, which allowed us to further transform the ester group and to access conformationally constrained benzyl- and phenethylamines, highly sought-after building blocks for the synthesis of new agrochems. The experimental part of the paper was very detailed, including the reaction process of 1-Bromo-2-isopropylbenzene(cas: 7073-94-1Application In Synthesis of 1-Bromo-2-isopropylbenzene)

A general and practical strategy to address the reaction between reactive and unreactive electrophiles by a combination of nickel and Lewis acid catalysis is reported. This strategy is used for the coupling of aryl bromides R1Br (R1 = 4-MeO2CC6H4, benzofuran-5-yl, indol-4-yl, etc.) with allylic alcs. R2CH:CHCR3R4OH (R2 = H, Me, Ph, etc.; R3 = R4 = H, Me; R3 = Me, Et, Ph, R4 = H) to form linear allylarenes R1CR3R4CH:CHR2. The reaction tolerates a wide range of functional groups (e.g. silanes, boronates, anilines, esters, alcs., and various heterocycles) and works with various allylic alcs. Complementary to most current routes for the C3 allylation of an unprotected indole, this method provides access to C2 and C4-C7 allylated indoles. Preliminary mechanistic experiments revealed that the reaction might start with an aryl nickel intermediate, which then reacts with Lewis acid activated allylic alcs. in the presence of Mn.

《B(C6F5)3-Catalyzed Hydrosilylation of Vinylcyclopropanes》 was written by Long, Peng-Wei; He, Tao; Oestreich, Martin. Recommanded Product: 1-Bromo-2-isopropylbenzeneThis research focused onvinylcyclopropane hydrosilane Lewis acid hydrosilylation catalyst; alkylsilane preparation. The article conveys some information:

A hydrosilylation of vinylcyclopropanes (VCPs) catalyzed by the strong boron Lewis acid B(C6F5)3 is reported. For the majority of VCPs, little or no ring opening of the cyclopropyl unit is observed Conversely, for VCPs with bulky R groups, such as ortho-substituted aryl rings or branched alkyl residues, ring opening is the exclusive reaction pathway. This finding is explained by the thwarted hydride delivery to a sterically shielded, β-silicon-stabilized cyclopropylcarbinyl cation intermediate. In addition to this study using 1-Bromo-2-isopropylbenzene, there are many other studies that have used 1-Bromo-2-isopropylbenzene(cas: 7073-94-1Recommanded Product: 1-Bromo-2-isopropylbenzene) was used in this study.
