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 catalyst loading in an operationally simple manner.

(Chemical Equation Presented) Two new ligands 1a,b are reported. Upon treatment with 1 equiv of NiCl2·(MeOCH2) 2, 1a,b give the corresponding Ni complexes. X-ray analysis of 1a·NiCl2 established that the NiClsu
