The known phosphonium chloride [HO(Me)CH]4PCl was prepared at ambient conditions from PH3 and acetaldehyde in aqueous HCl, and characterized by elemental analysis and 1H and 31{ 1H} NMR spectroscopy. Attempts to obtain the tertiary phosphine [HO(Me)CH]3P via reaction of [HO(Me)CH]4PCl with Na 2SO3 or Et3N in aqueous media under Ar revealed that [HO(Me)CH]3P is unstable and equilibrates with the secondary phosphine [HO(Me)CH]2PH and acetaldehyde. A 1:4 reaction of [HO(Me)CH]4PCl with NaHSO3 at room temperature under Ar affords first the oxide [HO(Me)CH]2P(O)H and then the phosphinic acid [HO(Me)CH]2P(O)OH. A 1:1 reaction of [HO(Me)CH]4PCl with Na2S2O3 affords the sulfide [HO(Me)CH] 3PS. 31{1H} and 1H NMR data for all the (α-hydroxyethyl)phosphorus species are reported for the first time.
