Title:
USE OF N,N-DISUBSTITUTED FORMAMIDE AS HALOGENATION CATALYST
Document Type and Number:
Japanese Patent JP2007231022
Kind Code:
A
Abstract:
To provide a new halogenation catalyst giving N,N-dialkylcarbamoyl halides which all have only very small volatility and are little dangerous for workers and environments.
A compound represented by the structural formula of Figure and their mixture are used as halogenation catalysts. Therein, R1and R2are independently selected from (a) a non-substituted or substituted 5 to 30C alkyl, 5 to 30C alkenyl, 5 to 30C alkynyl, or connection group, and (b) a non-substituted or substituted aminoalkyl and polyaminoalkyl and aminoalkenyl and polyaminoalkenyl; the substituent is independently selected from arbitrary functional groups not reacting with a basic compound to be halogenated and the halogenating agent used therein.
