Preparation of N-vinyl-o-sulfobenzimide by vinyl-interchange reaction was examined and the structure of unknown byproduct of this reaction was determined as N-1-acetoxyethyl-o-sulfobenzimide by infrared, nuclear magnetic resonance spectra and ultimate analysis. Reduction of N-vinylphthalimide by lithium aluminum hydride afforded isoindolin or its carbonate which was the product by hydrolysis of N-vinylisoindolin expected, and some resinous matter which was presumed as polymer of those. Dibromide of N-vinylsuccinimide was pyrolyzed under reduced pressure to form N-2-bromovinylsuccinimide by radical dehydrobromination. Nuclear magnetic resonance and ultraviolet absorption spectra of N-vinylsuccinimide, N-vinylphthalimide and N-vinyl-o-sulfobenzimide were determined and the relations to the structures were discussed. Spin-spin couplings of protons in vinyl group were AMX systems. Chemical shifts were affected by magnetic anisotropy of carbonyl and phenylene group. Absorption of imidogroup by π→π* transition was bathochromic in some extent by participation of vinyl group to it.
