Abstract
Abstract The reactions of 3,5-dinitro-4-chlorobenzotrifluoride (la) and 3,5-dinitro-2-chlorobenzotrifluoride (lb) with sulfur- and nitrogen-containing nucleophiles furnished the substituted benzothiazo-N-oxide (3,5) and S-(5-nitro-2-trifluoromethylphenyl-1,4-dithioglycolic ethyl ester(4). Similarly, the reaction of ethyl aminoacetate with lb gave substituted imidazol-N-oxide(8) and tetraazacyclooctanol(9). The possible mechanisms for the formation of 9 were discussed.
