Abstract

A convenient and cost-effective NaOH-promoted direct sulfenylation of pyrazolones with aryl thiols has been developed under mild and metal-free conditions. In this transformation, a range of valuable sulfenylated pyrazoles can be easily achieved in moderate to excellent yields, with high atom efficiency and good functional group tolerance.
