Stereoselective induction of an axiel chirality by Suzuki cross coupling of tricarbonyl(arene)chromium complexes with arylboronic acids
Abstract
Tricarbonyl(2,6-disubstituted-1-bromobenzene)chromium was treated with ortho-substituted phenylboronic acids in the presence of a palladium(0) catalyst to give mono-Cr(CO)3 complexes of biphenyl componds with a complementary axial chirality depending upon the nature of ortho-substituent of the phenylboronic acids
