Process for producing a propargylcarbinol compound of general formula (I):
where R¹ and R² independently represent hydrogen; C₁-C₁₅ alkyl which may be substituted with one or more halogen, hydroxyl, phenyl, phenoxy, phenyl or phenoxy substituted with one or more halogen, hydroxyl, alkoxy, phenoxy, dialkylamino and/or methylenedioxy aralkyloxy, dialkylamino, alkylthio, phenylthio, biphenyl and/or phenylalkyl; C₂-C₁₅ alkenyl which may be substituted with one or more halogen, hydroxyl, phenyl, phenoxy, phenyl or phenoxy substituted with one or more halogen, hydroxyl, alkoxy, phenoxy, dialkylamino and/or methylenedioxy, dialkylamino alkylthio, phenylthio, biphenyl and/or phenylalkyl; C₂-C₁₅ alkynyl which may be substituted with one or more halogen, hydroxyl, phenyl, phenoxy, phenyl or phenoxy substituted with one or more halogen, hydroxyl, alkoxy, phenoxy, dialkylamino and/or methylenedioxy, dialkylamino, alkylthio, phenylthio, biphenyl and/or phenylalkyl; C₃-C₁₅ cycloalkyl; C₄-C₁₅ cycloalkenyl; or phenyl, naphthyl, furyl or thienyl which may be substituted with one or more halogen, hydroxyl, alkyl, alkoxy, phenoxy, dialkylamino and/or methylenedioxy; or R¹ and R² together represent C₂-C₁₅ alkylene or alkenylene; with proviso that carbon atoms in the 1-positions of R¹ and R² are not together tertiary carbon atoms and that if one of R¹ and R² is furyl, the other does not represent hydrogen:
which comprises reacting a haloallylcarbinol compound of the formula (II):
wherein R¹ and R² are as defined above and X² represents chlorine, bromine or iodine, with a base. The present invention also relates to a process for producing the haloallylcarbinol compound. The above propargyl carbinol compound is useful as an intermediate for agrochemicals, pharmaceuticals, perfumes, resin monomers, and the like.
