摘要：

The reaction of chlordimethylphosphane or chlordiphenylphosphane and sodium tetraphenylborate with dicarbonyl(eta(5)-cyclopentadienyl)carbyne complexes of molybdenum and tungsten enables the direct conversion of a M=CR group into a M=C(R)-PR(2) unit providing dicarbonyl substituted eta(2)-phosphinocarbene complexes in high yields. In the absence of Na[BPh(4)] a base induced carbonyl carbene coupling reaction affords eta(3)-phosphinoketene complexes.
