Abstract:

Phosphinosilanes and phosphino halo silanes E.G. MeSiPH23 and MeSi PH2C12 have been obtained which can condense with amine borazane N-H bonds to form Si-N and B-N bonds cleanly. Polyborazane, polysilazane, and polyborosilazane 1,3,2-borodiazole C6H4 NH2BPh and 1,3,2-siladiazole C6H4NH 2R, R Me, Ph precursors and the new C6H4NH2BPh and 1,3,2-siladiazole C6H4 NH2R, R Me, Ph precursors and the new C6H4 NHSiPh220 heterocycle have been synthesized. Borazanes, silazanes, borosilazanes, phosphinosilanes, polyborazanes, polysilazanes, boron nitride, silicon nitride.
