Abstract

Treatment of fac-[Mn(CNPh)(CO)3(dmpm)]ClO4 (1) with KOH affords neutral phosphinite complex fac-[Mn(PMe2O)(CNPh)(CO)3(PMe3)] (2) as a result of P–C bond cleavage on the dmpm ligand, whereas when carrying out the reaction in the presence of iodine the diphosphinoketenimine derivative fac-[MnI(CO)3{(PMe2)2C[double bond, length as m-dash]C[double bond, length as m-dash]NPh}] (4) is obtained after deprotonation and further functionalization of the central carbon atom of the diphosphine.
