Abstract
Aroylisothiocyanates 2a-c were prepared via reaction of aroylchlorides 1a-c with ammonium thiocyanate in dry acetone. Treatment of appropriate compound 2a-c with o-phenylenediamine in refluxing acetone, afforded N,N’-(benzene-1,2-diyldicarbamothioyl)dibenzamide 3, N,N’-(benzene-1,2-diyldicarbamothioyl)bis(2,4-dichlorobenzamide) 4 and N,N’-(benzene-1,2-diyldicarba-mothioyl)bis(3,5-dinitrobenzamide) 5, respectively. Also, reaction of compounds 2a-c with 2,6-diaminopyridine afforded N,N’-(pyridine-2,6-diyldicarbamothioyl)bis dibenzamide 6, N,N’-(pyridine-2,6-diyldicarbamothioyl)bis(2,4-dichlorobenzamide) 7 and N,N’-(pyridine-2,6-diyldicarbamothioyl)bis(3,5-dinitrobenzamide) 8, respectively. Under similar conditions, compounds 2a-c were subjected to react with primary amines namely; 4-phenyl-4H-1,2,4-triazol-3-amine, 4-aminobenzoic acid, m-chloroanline, ethyl 2-amino-4,5,6,7-tetrahydro-1-benzothiophene-3-carboxylate, naphthylamine and o-anisidine, to afford N-[(4-phenyl-4H-1,2,4-triazol-3-yl)carbamothioyl]benzamide 9, 4-{[(2,4-dichlorobenzoyl)carbamothioyl]amino}benzoic acid 10, 2,4-dichloro-N-[(3-chlorophenyl)carbamothioyl]benzamide 11, ethyl2-{[(2,4-dichlorobenzoyl)carbamothioyl]amino}-4,5,6,7-tetrahydro-1-benzothio- phene-3-carboxylate 12, 2,4-dichloro-N-(naphthalen-1-ylcarbamothioyl) benzamide 13 and 2,4-dichloro-N-[(2-methoxyphenyl)carbamothioyl] benzamide 14, respectively. The reaction of furylisothiocyanate withnaphthylamine or o-phenylendiamine in refluxing acetone afforded N,N’-(benzene-1,2-diyldicarbamothioyl)difuran-2-carboxamide 15 and N-[(2-
