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

Abstract
The reaction of GaCl3 with three equivalents of But 2AsLi, But 2AsLi, or ArP(H)Li (Ar = 2,4,6-But 3C6H2) affords Ga(PBut 2)3, Ga(AsBut 2)3, and Ga[P(H)Ar]3, respectively, whilst the reaction of GaCl3 with one equivalent of But 2ELi and two equivalents of RLi results in dimeric phosphido- or arsenido-bridged compounds of the type [Ga(µ-EBut 2)R2]2(E = P, As; R = Me, Bun).
