13C-N.M.R.-Study of π-Electron Distribution in EnaminothioketonesThe 13C-n.m.r. spectra of a series enaminothioketones S=C(R1) —C(R2)=CH—NR3R4 have been studied and assigned. HMO - calculations of these compounds - pointing out the π-electron distribution - are discussed and compared with the 13C-chemical shifts. The investigated enaminothioketones are regarded as compounds with polymethine character and compared with the O - analogous merocyanines.
