Abstract
(EN)
Provided is a production method with which a haloalkyl acid halide can be efficiently produced. In the present invention, a compound represented by formula 1: CBrX1X2-(CY1Y2)n-CHBrZ is irradiated in the presence of oxygen and a radical with light having a wavelength in the range of 260-400 nm to oxidize the compound, whereby a haloalkyl acid halide represented by formula 2: CBrX1X2-(CY1Y2)n-C(O)Z is produced. In formulas 1 and 2, each of X1, X2, Y1, Y2, and Z independently represents a fluorine atom, a chlorine atom, or a bromine atom, and n represents an integer of 0-4.

L'invention concerne un procédé de production grâce auquel un halogénure d'acide haloalkyle peut être produit de manière efficace. La présente invention consiste à irradier un composé représenté par la formule 1 : CBrX1X2-(CY1Y2)n-CHBrZ, en présence d'oxygène et d'un radical avec une lumière ayant une longueur d'onde dans la plage de 260 à 400 nm pour oxyder le composé, ce qui permet de produire un halogénure d'acide haloalkyle représenté par la formule 2 : CBrX1X2-(CY1Y2)n-C(O)Z Dans les formules 1 et 2, chacun des X1, X2, Y1, Y2 et Z représentent indépendamment un atome de fluor, un atome de chlore ou un atome de brome, et n représente un nombre entier de 0 à 4.
