摘要

The phenolysis of 3-nitrophenyl 4-cyanophenyl thionocarbonate (1) and 4-nitrophenyl 4- cyanophenyl thionocarbonate (2) are subjected to a kinetic investigation in order to evaluate the nucleofugality of the corresponding leaving groups. For the reaction of 2 only 4- nitrophenoxide is obtained as leaving group. For the reaction of 1 the nucleofugality ratio 3- nitrophenoxide/4-cyanophenoxide is 1/3 from the corresponding T− intermediate. ...
