Conclusions
-
1.
Spectrophotometric studies have been carried out on the kinetics of alkaline hydrolysis of Me2P(S)OC6H4X-p thionephosphinates in water-acetonitrile solution at 25°C.
-
2.
It has been shown that the character of the combined effect of X structure and medium composition on ester reactivity undergoes a change at 50% acetonitrile.
-
3.
It is suggested that phosphorus atom attack by OH− anions is the limiting step in thionephosphinate alkaline hydrolysis.
