A carbon-bridged digallium compound as a chelating Lewis acid: Complexation of thiophenolate and benzoate anions by H5C6 - CH 2 - C(SiMe3)[Ga(CH2tBu)2] 2

The digallium compound H5C6 - CH 2C(SiMe3)(GaCl2)2 (6) is easily available by the 2-fold hydrogallation of phenyl(trimethylsilyl)ethyne with H - GaCl2. Its treatment with neopentyllithium gave the corresponding tetraneopentyl compound 7 by the replacement of all four chlorine atoms. Compound 7 has two coordinatively unsaturated gallium atoms attached to one carbon atom and, hence, is suitable to act as a chelating Lewis acid. Accordingly, tetrabutylammonium thiophenolate dissolved in 1,2-difluorobenzene reacted readily with 7 to afford the adduct 8, in which the sulfur atom of the thiophenolato group is coordinated by both gallium atoms to form a four-membered CGa2S heterocycle. A similar compound (9) was formed upon treatment of 7 with the benzoate anion. A slightly different structural motif compared to 8 resulted because each oxygen atom of the benzoate ligand is coordinated to one gallium atom to give a six-membered Ga2C2O2 heterocycle.
