Formation of 3-substituted 2-iminocyclopentanedithiocarboxylic acids and N-[amino(dimercapto)methyl]-2-methylcyclopentanimine from 2-substituted cyclopentanones. Some reactions of the imino-dithiocarb-oxylic acids
the corresponding 3-substituted2-iminocyclopentanedithiocarboxylicacids (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-iminocycl
