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.

Ethenyl amide compound production process

A cyanoketone derivatives of the following formula (1) ##STR1## which are characterized by excellent herbicidal activity and effectiveness against a variety of broad leafed weeds, including barnyard grass, green foxtail, velvet leaf, livid amaranth and hairy beggar ticks.
