| Abstract: | Batch data for hydrolysis of phenylthio-, phenylsulf inyl and phenylsul-fonyl acetates have been determined at various pH values and temperatures. The dual regression equations of Igk vs pH and 1/T were obtained. Neighbouring group participation in the hydrolysis of phenylthio acetates was discovered, and the relationships between anchimeric assistance(A) and pH were established. |

| Keywords: | phenylthio (phenylsulfinyl phenylsulfonyl) acetates hydrolysis effect of neighbouring group participation |
