Abstract

The very sterically encumbered secondary chlorophosphines Ar^Trip₂ P (Ph) Cl (Ar^Trip₂ = C₆ H₃ - 2, 6 (C₆ H₂ - 2, 4, 6 - Prⁱ₃)) and Ar^Mes₂ P (Ph) Cl (Ar^Mes₂ = C₆ H₃ - 2, 6 (C₆ H₂ - 2, 4, 6 - Me₃)) were prepared from the respective aryllithium precursors and PhPCl₂. Subsequent reduction of the chlorophosphines with Li[AlH₄] yielded the corresponding phosphines ArylP(Ph)H in high yield; these afforded the lithium salts ArylP(Ph)Li upon treatment with ⁿBuLi, and the synthesis and structural characterization of the monomeric terphenyl phosphide {[Ar^Mes₂ P (Ph)] Li (THF)₂} are described. Reaction of two equivalents of the lithium phosphide with SnCl₂ afforded a rare example of a monomeric Sn(II)-diphosphide, [Ar^Mes₂ P (Ph)]₂ Sn.
