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)
1-Bromo-2-isopropylbenzene(cas: 7073-94-1) belongs to organobromine compounds.Organobromine chemicals are produced naturally by an array of biological and other chemical processes in our environment. Organobromine compounds are produced naturally by marine creatures (sponges, corals, sea slugs, tunicates, sea fans) and seaweed, plants, fungi, lichen, algae, bacteria, microbes, and some mammals.
