Abstract
(EN)
The purpose of the present invention is to provide a method that enables efficient and safe production of an N-substituted trihaloacetamide which also serves as a synthetic intermediate for isocyanate compounds, carbamate compounds, urea compounds, etc. The method for producing an N-substituted trihaloacetamide according to the present invention is characterized by comprising a step for irradiating, with high energy light in the presence of oxygen, a mixture containing a primary amine compound and a tetrahaloethylene having at least one halogeno group selected from chloro-, bromo-, and iodo-.
(FR)
Le but de la présente invention est de fournir un procédé qui permet la production efficace et sûre d'un trihaloacétamide N-substitué qui sert également d'intermédiaire synthétique pour des composés d'isocyanate, des composés de carbamate, des composés d'urée, etc. le procédé de production d'un trihaloacétamide N-substitué selon la présente invention étant caractérisé en ce qu'il comprend une étape consistant à irradier, avec une lumière à haute énergie en présence d'oxygène, un mélange contenant un composé amine primaire et un tétrahaloéthylène ayant au moins un groupe halogéno choisi parmi chloro-, bromo- et iodo-.
(JA)
