Regioselective hydrodehalogenation of 3,5-dihaloisothiazole-4- carbonitriles: Synthesis of 3-haloisothiazole-4-carbonitriles
(2011)3,5-Dibromoisothiazole-4-carbonitrile 1 treated with Zn or In dust (5 equiv) and HCO2H undergoes regioselective hydrodebromination to give 3-bromoisothiazole-4-carbonitrile 3 in 70-74% yield. Similarly, 5-bromo and iodo ...
