摘要:
The reaction of M(CO)(3)(CH3CN)(3) (M = Mo, W) with an equimolar quantity of 1,2-bis(diphenylphosphino)benzene (dppb) results in formation of fac-M(CO)(3)(dppb) (CH3CN) (1, M = Mo, 73%; 2, M = W, 62%). Interaction of 1 or 2 with [60]fullerene in chlorobenzene at about 80 degrees C gives the isomerically pure isomers mer-M(CO)(3)(dppb)(eta(2)-C-60) (3, M = Mo, 76%; 4, M = W, 66%). All the new compounds 1-4 have been characterized by elemental analysis and spectroscopic methods, as well as by single-crystal X-ray diffraction analysis for 3 and 4.
