ABSTRACT:
A novel process for preparing the E-isomer of triazolyl styryl ketone derivative of the formula (I): ##STR1## is disclosed. The process includes treating the Z-isomer of the derivative which may contain the E-isomer of the derivative with an acid and an isomerization catalyst in an organic solvent, precipitating and separating the resulting salt of E-isomer from the solution, and decomposing the resulting precipitate to obtain the E-isomer of the derivative free from the acid. The E-isomer is useful for preparing the E-isomer of triazolyl styryl carbinol of the formula (II): ##STR2## which is useful as an antimicrobial agent, a herbicide, a plant growth regulator, or the like.
