Abstract
A process for producing an ethenyl amide compound, which comprises reacting a Schiff base compound having a carbon atom adjacent to a carbon atom constituting an imino group and at least one hydrogen atom on the carbon atom with an acylhalide at a reduced pressure while removing by-produced hydrogen halide by distillation to produce an ethenyl amide compound having an amide bond in the molecule and a double bond between carbons at .alpha.-position and .beta.-position with respect to the nitrogen atom of the amide bond.
