The reaction of o-aminobenzenethiol with carbonyl sulfide in the presence of triethylamine afforded an alternate route for the synthesis of 2-benzothiazolinone (1) in 97-98percent yield.The reaction of ammonium thiocarbamate (2) with 2-chlorocyclohexanone furnished the novel 4,5,6,7-tetrahydro-2-benzothiazolinone (3). 3-Ethoxy-2H-1,4-benzothiazin-2-one (7) was prepared by the reaction of o-aminobenzenethiol with diethyl oxalate.Possible pathways and supporting nmr, ir and mass spectra are discussed.
