Abstract
Benzothiazole 3-oxide (II) was synthesized, starting from its 2-methyl derivative, via the corresponding aldoxime, carbonitrile, imido ester and carboxylic acid. The reaction of the N-oxide II ; deoxygenations, reactions with various nucleophilic agents (tosyl chloride, Ac2O, C6H5MgBr, NaHSO3, NH2NH2·H2O and KCN·BzCl) involving some 1, 3-dipolarophiles (benzyne, C6H5NCO and tetracyanoethylene), and quaternizations were investigated and compared with those of the corresponding imidazole N-oxide.
