Claims (3)

1. Способ получения галогенметилбензоилцианидов общей формулы I
PH-CO-CN
где PH означает фенильный радикал, который замещен хлорметилом либо бромметилом и который при необходимости может нести еще 1-4 других, инертных для реакции радикала, из галогенметилбензоилхлоридов общей формулы II
PH-CO-Cl
отличающийся тем, что соединение формулы II подвергают взаимодействию с высвобождающим цианид соединением в присутствии кислоты Льюиса, при необходимости в инертном органическом растворителе либо разбавителе, и затем выделяют продукт способа.1. A method of producing halogenomethylbenzoyl cyanides of general formula I
PH-CO-CN
where PH denotes a phenyl radical, which is substituted by chloromethyl or bromomethyl and which, if necessary, can carry another 1-4 other, inert to the reaction of the radical, from halomethylbenzoyl chlorides of general formula II
PH-CO-Cl
wherein the compound of formula II is reacted with a cyanide releasing compound in the presence of a Lewis acid, optionally in an inert organic solvent or diluent, and then the product of the process is isolated. 2. Способ по п. 1, отличающийся тем, что переменная Ph представляет собой радикал
