Abstract
The two diastereoisomers of ArCH2P(S)(NMeR)Cl (Ar = 4-NO2C6H4, R* = C HMePh) react with Et2NH (0.2 mol dm(-3)) in CH2Cl2 to give mixtures of the diastereoisomers of ArCH2P(S)(NMeR)NEt2 in practically the same ratio (54.5:45.5 or 53:47); such non-stereospecificity points to a thi ophosphene intermediate ArCH=P(S)NMeR as the product-forming species.
