Kinetic and theoretical study on nucleofugality in the phenolysis of 3-nitrophenyl and 4-nitrophenyl 4-cyanophenyl thionocarbonates

- In the phenolysis of thionocarbonate 1 the permanent group drives the nucleofugality ratio.
- Carbon-basicities does not affect the reaction barriers for the phenolysis of 1.
- A two competing nucleofuges model assesses the nucleofugality ratio of the title reactions.
