Regioselective hydroamination of diphenylphosphorylallenes to synthesize b-aminophosphine oxides

الملخص EN

The regioselective hydroamination of diphenylphosphorylallenes has been developed using secondary amines as the amination reagents.

This reaction protocol could be realized under ligand and transition metal-free conditions at room temperature and is tolerated to a diverse range of diphenylphosphorylallenes and amine substrates, affording a series of b-amino phosphine oxides in good yields after the reduction of the enamine intermediates.
