Abstract
The reactions of primary and secondary phosphines with aldehydes and ketones have been studied with particular emphasis on the effects of substituents on phosphorus, and reaction conditions. Oxygen transfer reactions are observed with both primary and secondary phosphines thus providing a new route to secondary and tertiary phosphine oxides. The scope of these reactions has been defined in terms of substituents on phosphorus and the carbonyl reactant. In other cases, a range of more normal carbonyl adducts has been obtained including phosphines, phosphine hydrohalides, phosphonium salts and heterocycles and some of the factors which influence these reactions are described. The formation of α-alkoxy tertiary phosphine oxides has been noted in a few cases in the peroxide oxidations of α-hydroxy tertiary phosphines in neutral alcoholic solutions.
