摘要：

Treatment of methyl tantalocene complexes Cp2Ta(L)CH3 (4, L=Cp2Ta(=S)CH3, PMe3, ethylene) with azobenzene or azotoluene (ArN=NAr) leads to loss of L and formation of Cp2Ta(eta(2)-ArN=NAr)CH3 (5; the first structurally characterized group V azoarene complex) and Cp2Ta(=NAr)CH3 (6). Mechanistic studies show that complex 5 cannot be an intermediate in the formation of 6; an eta(1)-azoarene complex (8) is suggested as an alternative.
