Preparation of 1,1′-bis[(diphenylphosphino)methyl]ferrocene and its transition-metal complexes
Abstract
1,1′-Bis[(diphenylphosphino)methyl]ferrocene (dpmf). prepared from 1,1′-bis(chloromethyl)ferrocene and LiPPh2, reacted with [PdCl2(MeCN)2] to give [Pd2Cl2(dpmf )2]1, and treatment of 1 with [Pd3(2,6-Me2C6H3NC)6] in a 1 : 0.66 ratio in the presence of NH4PF6 and 2,6-Me2C6H3NC produced a macrocyclic complex [Pd4(2,6-Me2C6H3NC)8(dpmf )2]4+.
