Synthesis and structures of amino(triphenylgermyl) boranes and trihydro(triphenylgermyl) borates

The B-(triphenylgermyl)borazines 4a and 4b, the 1,2-bis(dimethylamino)-1,2-bis(triphenylgermyl)-diborane(4), 5, and the (2,2,6,6-tetramethylpiperidino)(triphenylgermyl)-boranes 6 and 7 were prepared by allowing LiGePh3 to react with the corresponding B-bromoborazines and aminochloroboranes, respectively. BH3 dissolved in thf readily adds to LiGePh3 generating Li(H3BGePh3), 8a, in thf solution. Addition of N-bases to the solution of 8a produced (tmen· thf)Li(H3BGePh3), 8b, and dimeric (py)2Li(H3BGePh3), 8c. The borazine ring in 4b is distorted into a boat shape. In 5 the NBGe planes are twisted against each other by 85°. Comparison with analogous (triphenylstannyl)boranes points to a more pronounced steric effect of the Ph3Ge group over the Ph3Sn group due to the shorter B-Ge bond. A fairly short B-Ge bond is found for the (triphenylgermyl)trihydroborates. The molecular structure of (Et2O)3LiGePh3 shows compressed C-Ge-C bond angles. Its molecular parameters fit well into the series LnLiEPh3 (E = Si, Sn, Pb). Wiley-VCH Verlag GmbH, 2001.
