W.; Ben-David, Yehoshoa; Milstein, David published 《Activation of Nitriles by Metal Ligand Cooperation. Reversible Formation of Ketimido- and Enamido-Rhenium PNP Pincer Complexes and Relevance to Catalytic Design》.Journal of the American Chemical Society published the findings.Reference of 2-(3-Bromophenyl)acetonitrile The information in the text is summarized as follows:
The dearomatized complex cis-[Re-(PNPtBu*)-(CO)2] (4) undergoes cooperative activation of CN triple bonds of nitriles via [1,3]-addition Reversible C-C and Re-N bond formation in 4 was investigated in a combined exptl. and computational study. The reversible formation of the ketimido complexes (5-7) was observed When nitriles bearing an alpha methylene group are used, reversible formation of the enamido complexes (8 and 9) takes place. The reversibility of the activation of the nitriles in the resulting ketimido compounds was demonstrated by the displacement of p-CF3-benzonitrile from cis-[Re-(PNPtBu-N=CPhpCF3)-(CO)2] (6) upon addition of an excess of benzonitrile and by the temperature-dependent [1,3]-addition of pivalonitrile to complex 4. The reversible binding of the nitrile in the enamido compound cis-[Re-(PNPtBu-HNC=CHPh)-(CO)2] (9) was demonstrated via the displacement of benzyl cyanide from 9 by CO. Computational studies suggest a stepwise activation of the nitriles by 4, with remarkably low activation barriers, involving precoordination of the nitrile group to the Re-(I) center. The enamido complex 9 reacts via β-carbon methylation to give the primary imino complex cis-[Re-(PNPtBu-HN=CC-(Me)-Ph)-(CO)2]-OTf 11. Upon deprotonation of 11 and subsequent addition of benzyl cyanide, complex 9 is regenerated and the monomethylation product 2-phenylpropanenitrile is released. Complexes 4 and 9 were found to catalyze the Michael addition of benzyl cyanide derivatives to α,β-unsaturated esters and carbonyls. In addition to this study using 2-(3-Bromophenyl)acetonitrile, there are many other studies that have used 2-(3-Bromophenyl)acetonitrile(cas: 31938-07-5Reference of 2-(3-Bromophenyl)acetonitrile) was used in this study.
According to other reports, 2-(3-Bromophenyl)acetonitrile(cas: 31938-07-5) is used in the preparation of diarylpyrimidines (DAPYs) as HIV-1 non-nucleoside reverse transcriptase inhibitors.Reference of 2-(3-Bromophenyl)acetonitrile
