Reactive Alkoxide Complexes of Groups 6 and 7 Metals
摘要:
Easily available alkoxo complexes [M(OR)(CO)(3)(bipy)] (M = Mn, Re) and [Mo(OR)(eta(3)-C3H5)(CO)(2)(phen)] react with dimethylacetylenedicarboxylate (DALA-D) to afford the Z-alkenyls resulting from DMAD insertion into the M-OR bonds. Evidence suggesting a nondissociative mechanism is presented.
