| titleOfInvention | Method for preferential production of geometric isomers and isolation method |
| abstract | A method for the preferential production of the Z form of a compound represented by the formula (5) [in the formula (5), Q, A and B have the same meanings as stated below], by reacting an acrylonitrile compound represented by the formula (1): [in the formula (1), Q represents unsubstituted or substituted phenyl or heterocyclyl, in particular 4-thiazolyl, 1- or 3-pyrazolyl, 1,3-oxazolyl-4-yl, phenyl, pyridyl or the like, A represents pyrazolyl, thiazolyl or the like, and B represents alkylcarbonyl or the like] with a compound represented by formula (3) [in the formula (3), B represents alkylcarbonyl or the like] or a compound represented by the formula (4) [in the formula (4), B has the same meaning as aforesaid], in the presence of a compound represented by the formula (2) [in the formula (2) R represents H, dimetylamino and the like], and a method for the isolation of geometric isomers, wherein, by dissolving or suspending a geometric isomer mixture of an acrylonitrile compound represented by the formula (5) in an alcohol or a solvent containing an alcohol, the E form is preferentially decomposed and the Z form is isolated, and wherein the decomposition product can be simply recovered by normal operations and reutilized. |
