Title:
PRODUCTION OF PROPARGYL CARBINOL COMPOUND
Document Type and Number:
Japanese Patent JP2946654
Kind Code:
B2
Abstract:
Process for producing a propargylcarbinol compound of general formula (I): where R<1> and R<2> 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 R<1> and R<2> together represent C2-C15 alkylene or alkenylene; with proviso that carbon atoms in the 1-positions of R<1> and R<2> are not together tertiary carbon atoms and that if one of R<1> and R<2> is furyl, the other does not represent hydrogen: which comprises reacting a haloallylcarbinol compound of the formula (II): wherein R<1> and R<2> are as defined above and X<2> 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.
