Abstract
NEW MATERIAL:A compound shown by the formulaI(R1 and R2 are alkyl, phenyl, halogen-substituted phenyl, etc.; R3 and R4 are alkyl, phenyl, or R3 and R4 are linked to neighboring N to form alkyl-substituted or unsubstituted heterocyclic monocyclic group).
EXAMPLE: N-(2-Isocyano-2-cyclohexylideneacetyl)piperidine.
USE: A herbicide. Having improved withering action on various kinds of weeds, especially broadleaf weeds, further high safety to various kinds of crops.
PROCESS: An α-formylaminoacrylic amide compound shown by the formulaII is reacted with a dehydrating agent such as phosphorus oxychloride in the presence of a deoxidizer (e.g., triethylamine, etc.) in a solvent such as benzene at -20W 50°C, to give a compound shown by the formulaI. The compound shown by the formula II, a raw material, is a novel compound, and obtained by reacting a ketone compound shown by the formula III with an α-isocyanoacetic amide compound shown by the formula IV.
