Resumo

Trimesitylazidosilane (1) and three new azidodisilanes, Mes2Si(N3)SiPh2-t-Bu (2), Me2Si(N3)SiMes2-t-Bu (3) and i-Pr2Si(N3)SiMes2-t-Bu (4), were prepared and photolyzed at 254 nm. Compound 1 photolyzes in glassy 3-methylpentane (3-MP) at 77 K or in 3-MP solution at −140°C to Mes2SiNMes (5) and a CH insertion product 6. Compounds 2−4 photolyze in 3-MP at low temperatures to give stable solutions of silanimines, R2SiNSiR2R′. Photolysis of 1−4 in the presence of alcohols yields alkoxyaminosilanes.
