Ring opening of 1,2-epoxyalkyldiphenylphosphine oxides with LiAlH4 gives 2-hydroxyalkyldiphenylphosphine oxides in good yield. This is the first example of ring opening of 1,2-epoxyalkyldiphenylphosphine oxides to give the corresponding 2-hydroxy derivatives.
(1-Alkyl-2-hydroxyethyl)diphenylphosphine oxides were synthesized from the corresponding (1-alkyl-2-oxoethyl)diphenylphosphine oxides in excellent yields. The structures of 2-hydroxy derivatives and their acetates were confirmed by elemental and spectral analyses.
