Reactions of GaX3 (X = BR, I) with As(SiMe3)3; Crystal Structures of I3Ga.As(SiMe3)3 and (I2GaAs(SiMe3)2)2
Abstract
Since our introduction in 1986 of the use of the silyl halide elimination reaction for forming the Gallium Arsenide bond, we have found it to be a versatile tool for the synthesis of interesting compounds. Using reagents of the general form RnAs(SiMe3)3-n and R'nGaX3-n (n = 0, 1, 2), a number of monomeric, dimeric, trimeric, and mixed bridge arsinogallanes have been prepared. However, some of the most basic chemical reactions in this series, viz. those between As(SiMe3)3 and GaX3, remained largely unexplored. Previously, we reported that reaction of GaX3 (X = Chlorine, Bromine) and As(SiMe3)3 in a 1:1 mole ratio yields products which, upon being heated with a cool flame, give microcrystalline GaAs. Others have shown that GaAs made in this way consists of particles small enough to be expected to exhibit quantum confinement effects.
