ABSTRACT:
Included is a process to prepare a 4-HALOmethyl-3,5-dihalo-2,6-disubstitutedphenol from a 4-methyl(substituted)phenol and a HALOgenating agent, in an aprotic organic diluent. The process is highly selective and efficient. For example, high purity 4-bromomethyl-3,5-dibromo-2,6-dimethylphenol can be prepared from 2,4,6-trimethylphenol and bromine, in bromochloromethane at high conversion.
