New silazane products result including oligomers and polymers. Suitable catalysts include metal carbonyl complexes and heterogeneous metal catalysts such as platinum on carbon. Immediate products of reaction such as products containing Si-H and N-H groups resulting from Si-N cleavage and Si-N products resulting from Si-H+N-H reactions undergo further reaction, resulting in many cases in a mixture of oligomers or of oligomers and polymers. The initial reactants may be open chain or ring compounds containing Si-N or Si-H+N-H in an open chain or in a ring or as pendant groups.
