摘要：

Reaction of [(eta(5)-C5H5)(CO)(2)(NO)Mo] (1) with alkynyllithium and [(CH3)(3)O]BF4 affords the vinylidene-molybdenum complex 2 along with the methoxy(alkynyl)carbene molybdenum complex 3. Both compounds are characterized by an X-ray crystal structure analysis. Due to axial and central chirality in the L(n)M=C=CR(2) moiety complex 2 is formed as a 2:1 mixture of two diastereomers. The formation of 2 and 3 can be understood in terms of a competitive attack of alkynyllithium at the carbonyl ligand and the molybdenum center.
