Synthesis of Cationic η2-Phosphinocarbene Complexes of Molybdenum and TungstenHerrn Professor Hubert Schmidbaur zum 60. Geburtstag gewidmet.The reaction of chlordimethylphosphane or chlordiphenyl-phosphane and sodium tetraphenylborate with dicarbonyl(η5-cyclopentadienyl)carbyne complexes of molybdenum and tungsten enables the direct conversion of a M=CR group into a M=C(R)—PR2 unit providing dicarbonyl substituted η2-phosphinocarbene complexes in high yields. In the absence of Na[BPh4] a base induced carbonyl carbene coupling reaction affords η3-phosphinoketene complexes.
