In order to examine their antimicrobial activity, new N-derivatives of chlorine-substituted 4-thiocyanatoanilines (A) and 2-amino-6-chlorobenzothiazole (B) were prepared by the reaction of compound A or B with haloacetyl halides, alkyl chloroformates, phenoxyacetyl chlorides, phenyl isocyanates, or arylaldehydes.

regioselective thiocyanation of various substituted anilines and indoles is described. The reaction performed both on and off the alumina surface under microwave conditions. Microwave irradiation reactions under solvent-free conditions resulted in a “green-chemistry” procedure, by which thiocyanation was achieved. In comparison to other reported methods for regioselective thiocyanation of anilines and
