Abstract:

Preparative and mechanistic aspects of polysilanes and polyphosphazenes are reviewed based on the several synthetic methods developed in the authors laboratories. Polysilanes are prepared by sonochemical reductive coupling, modifications and ring opening polymerization. Polyphosphazenes are prepared by the catalyzed polycondensation of phosphoranimines and by the direct reaction of phosphonites and phosphinites with silyl azides.
