摘要

Rather than proceeding through a Michael-type or 1,4-addition, thioacetic acid adds across unsaturated aldehydes in an autocatalytic manner and involving a double exotherm, as demonstrated by both adiabatic and reaction calorimetry NMR studies show that an intermediate acyl-thio-hemiacetal is involved and that the product continues to react competitively with thioacetic acid
