The novel trisilylamine [H(CH3)2Si]3N is prepared by reacting together, in the presence of pyridine, a picoline, or a tertiary amine as acid acceptors, [H(CH3)2Si]2NH or [R3Si]2NH with H(CH3)2SiCl or R3SiCl and recovering the product, e.g. by distillation. At least one of the reactants must contain the H(CH3)2Si-group, and R is any monovalent hydrocarbon radical. Preferably, all the organic radicals bonded to silicon are methyl radicals; the disilylamine is preferably present in molar excess, and the acid acceptor is preferably present in 5 to 15% molar excess. |
