Organometallic compounds of Group 13 elements containing the ligand C(SiMe3)2(SiMe2C5H4N-2)

The lithium derivative (1) reacted with AlCl3 or Me2AlCl to give, respectively, the monomeric compounds (2a) and (2b). The product from reaction with commercially available GaBr3 was the analytically pure monomeric heterocycle (3), indicating that the starting halide had been partially hydrolysed before use. The reaction between 1 and commercially available InCl3 gave a homogenous white solid (4) with X = Cl (59%) or OH (41%). The X-ray crystal structures of 2a, 3, and 4 have been determined.
