Perfluoroalkyl complexes of palladium and platinum

Abstract

Treatment of the zero-valent platinum or palladium complexes (Ph₃P)₄M or (Ph₂PCH₂CH₂PPh₂)₂M with perfluoroalkyl iodides represents a convenient synthesis of the perfluoroalkyl(iodo)-compounds (Ph₃P)₂M(R_F)I or diphosM(R_F)I (R_F= CF₃, C₂F₅, or C₃F₇). The new compounds are somewhat insoluble in organic solvents, but are stable in air. An oxidative-addition reaction also occurs between pentafluorobenzoyl chloride and tetrakis(triphenylphosphine)platinum.
