On the Reaction of C(PPh3)2 with [Co2(CO)8]: Formation and Structure of an Unusual Tetranuclear Cluster


The reaction of the carbodiphosphorane C(PPh3)2 (1) with [Co2(CO)8] results in the formation of the salt-like complex (HC{PPh3}2)[Co(CO)4] (2) in high yield if THF is used as the solvent. The proton of the cation stems from THF degradation. When the reaction is carried out in toluene, the tetranuclear cluster [Co4(CO)10(PPh3)(μ4-CCPPh3)] (3) is formed in… (More)
