Selective mono-debromination of polybromoalkyl aryl ketones

摘要

A process for selectively debrominating polybromoalkyl aryl ketones and polybromoalkyl heteroaryl ketones is disclosed. The process comprises contacting an alpha-polybrominated ketone with an alkali metal sulfite in the presence of a CSB2/SB-CSB6/SB alkylcarboxylic acid to obtain a selectively mono-debrominated product.
