摘要：

Chromium complexation of a 2,6,2'-trisubstituted biphenyl compound gave four mono-Cr(CO)3 and one di-Cr(CO)3 complexation products in a variable ratio depending on the reaction conditions. However, cross-coupling of (2,6-disubstituted-1-bromobenzene)Cr(CO)3 with 2-substituted phenylboronic acid catalyzed by palladium(0) produced a stereoselectively coupled product without the formation of the axial isomer. The crystal structures of these chromium complexes were determined by X-ray crystallography.
