Provided is a novel process for selectively producing the E-geometrical isomer or Z-geometrical isomer of an oximino compound useful as a medicine or agrochemical. In the process, a mixture of geometrical isomers of an oximino compound represented by formula (EZ)-1 is mixed with an acidic compound to produce the E-isomer of the oximo compound represented by the formula (E)-1 or the Z-isomer of the oximino compound represented by the formula (Z)-1 in high yields with high stereoselectivity.

Method for producing geometrical isomer of oximino compound

The present invention provides a heterocyclic amide compound of Formula (1), and an agricultural chemical containing it, particularly a herbicide: in which Q is an aromatic heterocycle of any one of Q-1 to Q-5, W is an aromatic heterocycle of W-1, W-2, or W-3, X is an oxygen atom, etc., Ris a hydrogen atom, a halogen atom, or Calkyl, etc., Ris a hydrogen atom, Ris Calkyl, Ris a halogen atom, or Calkyl, etc., Ris Chaloalkyl, Ris a hydrogen atom, etc., R, R, Rand Rare each independently a hydrogen atom, or Calkyl, etc., R, Rand Rare each independently a hydrogen atom, or Calkyl, etc., and n is an integer of 0, 1, 2 or 3.
