Abstract
1 nucleo- philic substitution reactions of dimethyl thiophosphinic chloride with anilines are studied kinetically. To clarify the (thio)phosphoryl transfer mechanism, as well as to compare the reactivity, selectivity parameters, and deuterium kinetic isotope effects (DKIEs) of dimethyl phosphinic chloride (Me2P(=O)Cl; 2), 1i diphenyl thiophosphinic chloride (Ph2P- (=S)Cl; 3), 1e and diphenyl phosphinic chloride (Ph2P(=O)Cl; 4), 1d we investigate the aminolysis of dimethyl thiophosphinic chloride (Me2P(=S)Cl; 1) with substituted anilines (XC6H4NH2) and deuterated anilines (XC6H4ND2) in acetonitrile at 55.0 o C.
