Abstract
The catalytic activities of nine neutral nickel and palladium sigma -acetyl
ide complexes [M=(C=CR)(2)(PR'(3))(2), M= Ni, Pd; R =Ph, CH2OH, CH2OOCH3, C
H2OOCPh, CH2OOPhOH-o; R'= Ph, Bu] are compared. Among them, Ni(C=CPh)(2)-(P
Bu3)(2) shows the highest catalytic activity and gives the polystyrene with
high molecular weight (M-w=188800) and a syndio-rich microstructure. The c
atalytic behavior of transition metal acetylides is related to metal, phosp
hine, and alkynyl ligands bonded to the metal atoms.
