Synthesis and Characterization of Compounds Containing the As(SiMe3)2 Bridging Group: Crystal Structures of t-Bu2GaAs(SiMe3)22 and t-Bu2GaAs(SiMe3) 2Ga(t-Bu)2Cl

Abstract

Abstract--t-Bu2GaAs(SiMe3)22 (I) and t-Bu2GaAs(SiMe3)2Ga(t-Bu)2Cl were not produced from reaction mixtures of t-Bu2GaCl with (Me3Si)3As (1:1 and 2:1 mole ratio mixtures) and only starting materials were recovered. However, t- Bu2GaC1 reacts with LiAs(SiMe3)2 2THF. Compound II is the fifth example of a compound containing the Ga-As-Ga-X (X = Cl, Br) core, and the second wherein the organogallium four-membered ring with arsenic, halogen mixed bridging is not puckered. In addition to partial elemental analyses and Nuclear Magnetic Resonance spectroscopic characterization data, the molecular structures have been elucidated by single crystal X ray diffraction methods.
