摘要： 前文曾报导Fischer型钼的卡宾络合物对炔烃的催化聚合作用比钨的卡宾络合物高[1,2]。含有σ-键的钼、钨络台物对炔烃的催化聚合作用,至今未见报导。我们按文献合成了四个含σ-键的钼、钨络合物,试验了它们对炔烃的催化聚合作用。

Abstract: The catalytic polymerizations of alkyne in the presence of η5-C5H5M(CO)3Rx (M = Mo,W; R = CH3, C2H5) have been studied. The results showed that these complexes possess catalytic activities for the polymerization and copolymerization of monosubstituted acetylene. Catalytic mechanisms have been preliminarily discussed. It is suggested that the active species are metal-carbenc.
