The effect of the substituent on the rate of the opening of substituted thiiranes by phenol was investigated.The direction of opening of the thiirane ring varies, depending on the electronic character of the substituent; for substituents whose electronic effect is transmitted by an induction mechanism the product corresponding to opening of the thiirane ring according to the Krasuskii rule predominates in the reaction mass.For thiiranes with substituents containing a ?-electron system the opening of the three-membered heterocycle takes place with the formation ofanomalous reaction products.The ratio of the reaction paths to the formation of the isomeric oxathiaalkenes was determined.
