General description
Methyl 3-bromobenzoate is an aryl bromide. It undergoes stereoconvergent cross-coupling with potassium trifluoro(1-phenylethyl)borate to form 1,1-diarylethane derivative. The Negishi cross-coupling reaction between methyl 3-bromobenzoate and diarylzinc reagents in the presence of a palladium catalyst has been reported. Methyl-3-bromobenzoate can be converted into the corresponding benzonitrile using dichloro[bis{1-(dicyclohexylphosphanyl)piperidine}]palladium as a C-C cross-coupling catalyst and K4[Fe(CN)6] as a cyanating agent.

Dichloro[bis{1-(dicyclohexylphosphanyl)piperidine}]palladium [(P{(NC(5)H(10))(C(6)H(11))(2)})(2)PdCl(2)] (1) is a highly active and generally applicable C-C cross-coupling catalyst. Apart from its high catalytic activity in Suzuki, Heck, and Negishi reactions, compound 1 also efficiently converted various electronically activated, nonactivated, and deactivated aryl bromides, which may

The routine application of C(sp3)-hybridized nucleophiles in cross-coupling reactions remains an unsolved challenge in organic chemistry. The sluggish transmetalation rates observed for the preferred organoboron reagents in such transformations are a consequence of the two-electron mechanism underlying the standard catalytic
