Abstract
2-Ethyl, 2-isopropyl. 2-cyclopentyl. and 2-cyclopentylidenecyclopentanones, when treated with carbon disulphide and ammonia, gave the corresponding 3-substituted 2-iminocyclopentanedithiocarboxylic acids (5)–(7) and (9). Under the same conditions, 2-methylcyclopentanone gave 2-imino-3-methylcyclopentanedithiocarboxylic acid (2), and N-[amino(dimercapto)methyl]-2-methylcyclopentanimine (3), and 2-isopropylidenecyclopentanone gave7a-amino-4,4-dimethylperhydrocyclopenta[e][1,3]thiazine-2-thione (8). Reactions of the 2-iminocyclopent-anedithiocarboxylic acids with hydrazine, thiosemicarbazide, picryl chloride, and phenyl isothiocyanate have also been investigated.Keywords
