Ligand substitution at five-co-ordinate centres. Effect of oxidation state change on mechanism
Abstract
The mechanism of replacement of tri-p-tolylphosphine by tri-n-butyl phosphite in the five-co-ordinate 1,2-dithiolene complex [Co{P(tolyl)3}{S2C2(CF3)2}2]z is associative when z= 0 and dissociative when z=–1.
