Catalyst-free synthesis of α-thioacrylic acids via cascade thiolation and 1,4-aryl migration of aryl alkynoates at room temperature
Abstract
A simple and facile catalyst-free method for the construction of α-thioacrylic acids has been developed from readily-available aryl alkynoates and thiols at room temperature. Various α-thioacrylic acids could be conveniently and efficiently obtained in moderate to good yields via cascade thiolation and 1,4-aryl migration of aryl alkynoates in the absence of any catalyst and additive.
