The various α-aminophosphonates have been prepared from tertiary aromatic and aliphatic amines with P(O)H compounds via a tert-butyl hydroperoxide mediated cross-dehydrogenative coupling reaction, eliminating the need for transition-metal catalysts. The oxidation of tertiary amine by tert-butyl hydroperoxide generates an iminium cation intermediate. A further addition of P(O)H compound to iminium cation
