The use of PhSZnBr as sulfenylating agent in a solvent-free protocol to prepare thiolesters in excellent yields from acyl chlorides is reported. The products were efficiently obtained by grinding the neat reagents for 5 min in a mortar. DFT calculations showed that the coordination of solvent molecules to the metal center of PhSZnBr results in the destabilization of the frontier MOs, thus reducing
