Abstract 1 H, IR, and electronic absorption spectroscopy and X-ray diffraction analysis were used to establish that 1-acetyl-1-nitro-2-phenyl-and 2-(p-methoxyphenyl) ethenes have Z configuration, and their 2-(pN, N dimethylaminophenyl)-substituted analog exists in chloroform-d 3 as a mixture of Z and E isomers. The reactions of gem-acetylnitroethenes with N-methylpyrrole were shown to involve alkylation at the C 2-reaction center of the ...
