ed synthesis of a specific class of 1,2,4-dithiazolidines from β-ketothioamides is devised employing eosin Y as a photoinitiator at ambient temperature in an open pot. The reaction proceeds via an in situ-generated thiyl radical followed by dimerization/deaminative cyclizationcascade, enabling the creation of a dithiazolidine ring through successive formation of S–S and N–C bonds undermetal- and
