In 2009,Chemistry – A European Journal included an article by Gendrineau, Thomas; Demoulin, Nicolas; Navarre, Laure; Genet, Jean-Pierre; Darses, Sylvain. COA of Formula: C6H4BBrF3K. The article was titled 《Rhodium-Catalyzed Formation of Stereocontrolled Trisubstituted Alkenes from Baylis-Hillman Adducts》. The information in the text is summarized as follows:

Efficient and general conditions for the formation of stereodefined trisubstituted alkenes by using the rhodium-catalyzed reaction of unactivated Baylis-Hillman adducts with either organoboronic acids or potassium trifluoro(organo)borates are reported (see scheme). We report here efficient and general conditions for the formation of stereodefined trisubstituted alkenes using the rhodium-catalyzed reaction of unactivated Baylis-Hillman adducts with either organoboronic acids and potassium trifluoro(organo)borates. The use of the [{Rh(cod)OH}2] precursor gave very fast coupling reactions under low catalyst loading, very mild reaction conditions (from room temperature up to 50 °C) and without the need of addnl. phosphane ligands. Based on the new reaction conditions, the reaction, originally limited to Baylis-Hillman adducts derived from esters, could be extended to a large variety of Baylis-Hillman adducts, bearing either keto, cyano or amido functionalities. Moreover, the reaction of Baylis-Hillman adducts bearing esters functionality was improved and could be conducted at lower temperature using lower catalyst loading. In addition to this study using potassium (3-bromophenyl)trifluoroborate, there are many other studies that have used potassium (3-bromophenyl)trifluoroborate(cas: 374564-34-8COA of Formula: C6H4BBrF3K) was used in this study.

Formula: C6H4BBrF3KOn September 7, 2011 ,《Expanded Substrate Scope and Improved Reactivity of Ether-Forming Cross-Coupling Reactions of Organotrifluoroborates and Acetals》 was published in Journal of the American Chemical Society. The article was written by Vo, Cam-Van T.; Mitchell, T. Andrew; Bode, Jeffrey W.. The article contains the following contents:

Mixed acetals and organotrifluoroborates undergo BF3·OEt2-promoted cross-couplings to give dialkyl ethers under simple, mild conditions. A survey of reaction partners identified a hydroxamate leaving group that improves the regioselectivity and product yield in the BF3·OEt2-promoted coupling reaction of mixed acetals and potassium alkynyl-, alkenyl-, aryl- and heteroaryltrifluoroborates to access substituted dialkyl ethers. This leaving group enables the reaction to proceed rapidly under mild conditions (0 °C, 5-60 min) and permits reactions with electron-deficient potassium aryltrifluoroborates that are less reactive with other acetal substrates. A study of the reaction mechanism and characterization of key intermediates by NMR spectroscopy and X-ray crystallog. identified a role for the hydroxamate moiety as a reversible leaving group that serves to stabilize the key oxocarbenium intermediate and the need for a slight excess of organodifluoroborane to serve as a catalyst. A secondary role for the boron nucleophile as an activating ligand was also considered. These studies provide the basis for a general class of reagents that lead to dialkyl ethers by a simple, predictable cross-coupling reaction. In the experiment, the researchers used potassium (3-bromophenyl)trifluoroborate(cas: 374564-34-8Formula: C6H4BBrF3K)

potassium (3-bromophenyl)trifluoroborate(cas: 374564-34-8) belongs to organobromine compounds.The reactivity of organobromine compounds resembles but is intermediate between the reactivity of organochlorine and organoiodine compounds. Formula: C6H4BBrF3K Dehydrobromination, Grignard reactions, reductive coupling, Wittig reaction, and several nucleophilic substitution reactions are some of the principal reactions which involve organic bromides.

The article was titled 《Direct access to ketones from aldehydes via rhodium-catalyzed cross-coupling reaction with potassium trifluoro(organo)borates》.Recommanded Product: 374564-34-8 The article contains the following contents:

A direct cross-coupling reaction of aromatic aldehydes with potassium trifluoro(organo)borates afforded diaryl ketones in high yields and under mild conditions in the presence of a rhodium catalyst and acetone. This reaction, involving a formal aldehyde C-H bond activation, is believed to proceed via a Heck-type mechanism followed by hydride transfer to acetone. In the experiment, the researchers used many compounds, for example, potassium (3-bromophenyl)trifluoroborate(cas: 374564-34-8Recommanded Product: 374564-34-8)

Mitchell, T. Andrew; Bode, Jeffrey W. published their research in Journal of the American Chemical Society on December 23 ,2009. The article was titled 《Synthesis of Dialkyl Ethers from Organotrifluoroborates and Acetals》.Formula: C6H4BBrF3K The article contains the following contents:

The formation of ethers by C-O bond formation under harsh basic or acidic conditions is an entrenched synthetic disconnection in organic chem. We report a strategic alternative that involves the BF3·OEt2-promoted coupling of stable, easily prepared acetals with widely available potassium aryl-, alkenyl-, and alkynyltrifluoroborates. This fast, operationally simple process offers straightforward access to dialkyl ethers, many of which would be difficult to prepare using classical methods. The use of MOM-protected alcs. and acetal-protected aldehydes enables ether formation without recourse to protecting-group manipulations or strong bases. In addition to this study using potassium (3-bromophenyl)trifluoroborate, there are many other studies that have used potassium (3-bromophenyl)trifluoroborate(cas: 374564-34-8Formula: C6H4BBrF3K) was used in this study.
