Silicon–nitrogen compounds. Part V. Diphenylamino-derivatives of silane

Abstract

Diphenylamine reacts with iodosilane and di-iodosilane to give diphenylaminosilane, SiH₃NPh₂, and bisdiphenylaminosilane, SiH₂(NPh₂)₂, respectively. Some physical and chemical properties of the compounds are reported: in particular, both are very weak Lewis bases. Both compounds are thermally stable in vacuo at 310°; SiH₃NPh₂ decomposes at 355 or 380° to give hydrogen, silane, SiH₂(NPh₂)₂, and diphenylamine, while benzene and hydrogen are evolved at 450°. The use of SiH₃NPh₂ in amine exchange reactions is investigated.
