摘要

Two air-stable Ni, Cr-heterobimetallic catalysts have been prepared from ligands 7 and 11, obtained from scyllo-inositol in four and three steps, respectively. Both catalysts smoothly promote Ni/Cr-mediated coupling reactions with a ca. 1: 1 molar ratio of coupling partners. The catalyst derived from 11 exhibits a better catalytic profile, thereby allowing Ni/Cr- mediated coupling reactions to be achieved with a wide range of substrates at a low ...
