Syntheses and Crystal Structures of Copper and Silver Complexes with the Ylide Ph₃PCHP(O)PPh₂ as Ligand

Abstract

Abstract. The reactivity of the hydrolysis product of hexaphenylcarbodiphosphorane, PPh 3 CHP(O)Ph 2 , towards different soft Lewis acids, such as CuI and Ag [BF 4 ] are reported. While CuI exclusively binds at the ylidic carbon atom, reaction of the silver cation in CH 2 Cl 2 leads to proton abstraction from the solvent to give the cation
