| Abstrakt: |
2,5-Dimethyl- and 2-ethyl-5-methyl-1,3-benzodithiolium perchlorates react with dimethylformamide and N-phenyl-N-methylaminoacrolein to give monoiminium salts, the hydrolysis of which yields the corresponding aldehydes. The trans-transoid structure ofß-formylvinyl-substituted 2-methylenebenzo-1,3-dithioles was established by a comparison of the experimental and calculated dipole moments, absorption maxima, and intensities of the electron transitions and also by analysis of the PMR spectra. |
