Reactions of Dimethyl N-Aroyl(Hetaroyl)carbimidodithioates with Carbanions CH-acidic Compounds
Reactions of dimethyl N-aroyl(hetaroyl)carbimidodithioates 1 with carbanions 2 present new possibilities to synthesize 3-acyl-amino-3-methylthio-2-subst.-acrylnitriles 3 by monosubstitution of methylthiogroup.The reaction of 1 with 2-alkyl-benzothiazolium salts 4 yield deeply coloured N-acyl-(2,3-dihydrobenzothiazole-2-yliden)thioacetimido acid-methylates 5 of the 2-subst.-benzothiazoliumperchlorates 6.The structures of the final products are determined by i.r.-, 1H-n.m.r.- and u.v.-spectra.

New Synthesis of Dimethyl-cinnamoylimino-dithiocarboxylate and Reactions with Nucleophiles
A new general synthesis of dimethyl-cinnamoylimino-dithiocarboxylate 1d is possible by reaction of 4-nitro-cinnamoylamide with carbon disulfide in the presence of sodium hydride and following alkylation.With the unsubstituted dimethyl-cinnamoylimino-dithi
