Mono-and di-nuclear phosphido and arsenido complexes of gallium; Ga(EBut2)3, Ga[PH(2,4,6-But3C6H2)]3 and [Ga(µ-EBut2)R2]2, (E = P, As; R = Me, Bun)

Abstract

The reaction of GaCl₃ with three equivalents of Bu^t₂AsLi, Bu^t₂AsLi, or ArP(H)Li (Ar = 2,4,6-Bu^t₃C₆H₂) affords Ga(PBu^t₂)₃, Ga(AsBu^t₂)₃, and Ga[P(H)Ar]₃, respectively, whilst the reaction of GaCl₃ with one equivalent of Bu^t₂ELi and two equivalents of RLi results in dimeric phosphido- or arsenido-bridged compounds of the type [Ga(µ-EBu^t₂)R₂]₂(E = P, As; R = Me, Buⁿ).
