Abstract

Abstract Treatment of 3-aryl-2-thioxo-1, 3-thiazolidin-4-ones 1 with CN− and NCO− effected the ring cleavage providing [(cyanocarbonothioyl) amino] benzenes 4 and arylisothiocyanates 5, respectively. Similar treatment of 5-(2-aryl-2-oxoethyl) derivatives 2 afforded 2, 4-bis (2-aryl-2-oxoethylidene) cyclobutane-1, 3-diones 6 along with each of the preceding products. Treatment of the respective (E, Z)-5-(2-aryl-2-oxoethylidene) ...
