Modular assembly of 4-trifluoromethyl substituted 2-imino-1,3-oxathioles via cobalt(II)-based metalloradical catalysis

We report herein a cobalt(II) metalloradical-mediated cycloaddition of α-trifluoromethyl-α-diazoketone with isothiocyanate, which led to the modular formation of 4-trifluoromethylated 2-imino-1,3-oxathioles from easily accessible starting materials with high efficiency. Moreover, the...
