The synthesis of S,N-acetals of formyldiphenylphosphine oxide 2 is described. The stable lithiated anions of these acetals were applied in a Horner-Wittig reaction with several structural types of aldehydes. The resulting S,N-ketene acetals 1 were obtaine
The synthesis of α-amino-substituted diphenylphosphine oxides

Four methods with differing but overlapping specificity are described for the synthesis of α-unsubstituted as well as α-substituted (aminomethyl)diphenylphosphine oxides.The first method is based on the Arbusov reaction, the second on a Mannich-type condensation of diphenylphosphine oxide with aldehydes and secondary amines, the third on the addition of Ph2P(O)H to enamines and the fourth on the reaction of anions derived from α-unsubstituted (aminomethyl)diphenylphosphine oxides with various electrophiles.
