[(2-(Diphenylphosphino)ethyl)cyclopentadienyl]tricarbonylmetalates: Supporting Ligands for Reactions at Group VI Metal−Copper Bonds
摘要:
Salts of [(2-(diphenylphosphino)ethyl)cyclopentadienyl]tricarbonylmetalates react with CuCl to afford useful intermediates that permit installation of phosphines at copper(I), in a rare instance of nucleophilic attack at heterobimetallic M-Cu bonds without concomitant heterolytic cleavage.
