报道了紫外激光诱导金属羰基化合物M(CO)_3在不同卤代烃中解离进行α-H的烯烃和炔烃多相和均相催化聚合的研究.研究结果表明:W(CO)_6在CCl_4中激光解离生成的多相催化剂能有效地催化聚合具有活泼α-H的端基烯烃;W(CO)_6在CH_3I激光解离生成的均相催化剂能进行苯乙炔的均相催化聚合,并且所得到聚合物的结构完全不同于W(CO)_6在CCl_4中激光解离多相催化聚合苯乙炔得到的聚合物的结构。此外,还对M(CO)_6在卤代烃中的解离产物及聚合过程进行了详细的分析和讨论。
Reported the UV laser-induced metal carbonyl M (CO) _3 dissociation of different halogenated hydrocarbons α-H olefin and alkyne heterogeneous and homogeneous catalytic polymerization study results show that: W (CO) _6 in The heterogeneous catalysts produced by laser dissociation in CCl_4 can catalyze the polymerization of terminal olefins with active α-H efficiently. The homogeneous catalysts produced by W_ (CO_) _6 laser dissociation can carry out the homogeneous catalytic polymerization of phenylacetylene, And the structure of the obtained polymer is completely different from that of the polymer obtained by laser-dissociating heterogeneous catalytic polymerization of phenylacetylene with W (CO) 6 in CCl 4. In addition, the dissociation products and polymerization of M (CO) 6 in halogenated hydrocarbons were also analyzed and discussed in detail.
