Title (EN) METHOD FOR PREPARING THIOCARBOXYLIC ACID S-(FLUOROALKYL) ESTER
(FR) PROCÉDÉ DE SYNTHÈSE DE THIOCARBOXALATE DE S-(FLUOROALKYLE)
(JA) チオカルボン酸S-(フルオロアルキル)エステルの製造方法
Abstract: front page image
(EN)A novel method for preparing a thiocarboxylic acid S-(fluoroalkyl) ester represented by formula (III) [wherein R1 is methyl, ethyl or phenyl; and R2 is C1-5 fluoroalkyl], characterized by reacting a thiocarboxylic acid represented by formula (I) [wherein R1 is as defined above] with a fluoroolefin represented by formula (II) [wherein R2 is as defined above] in the presence of a radical generator.
(FR)La présente invention concerne un nouveau procédé de synthèse d'un thiocarboxalate de S-(fluoroalkyle) de formule (III) [où R1 représente un groupement méthyle, éthyle ou phényle ; et R2 représente un groupement fluoroalkyle en C1-5], caractérisé par la réaction d'un acide thiocarboxylique de formule (I) [où R1 est tel que défini ci-avant] avec une fluoroléfine de formule (II) [où R2 est tel que défini ci-avant] en présence d'un générateur de radicaux.
(JA) 式(I)で示されるチオカルボン酸〔式中、R1はメチル基、エチル基またはフェニル基を表す。〕と式(II)で示されるフルオロオレフィン〔式中、R2はC1-C5フルオロアルキル基を表す。〕とを、ラジカル発生剤存在下に反応させることを特徴とする式(III)で示されるチオカルボン酸S-(フルオロアルキル)エステル〔式中、R1およびR2は前記と同じ意味を表す。〕の新規な製造方法を提供する。
