Systematic ligand effects on the rates of CO substitution of (.eta.5-C5H4CO2Me)Co(CO)2

摘要: The reaction of (η 5 -C H 4 CO 2 Me)Co(CO) with phosphines and phosphites gives the monosubstituted products Me)Co(CO)L. proceeds solely by a second-order process, first order in metal complex nucleophile. effects phosphorus(III) ligands on kinetics this have been studied. electronic profile shows division into one group that no steric another effects. former includes alkylphosphines mixed alkylarylphosphines as well triaryl phosphites. intrinsic reactivity properties Me )Co(CO) are compared
