Abstract

The halides according to the invention are meta-phenoxybenzylidene bromide and chloride. They are prepared from meta-phenoxytoluene by reaction with two equivalents of N-chloro- or N-bromoacetamide, N-chloro- or N-bromosuccinimide, chlorine or bromine at 30 - 150 DEG C in an inert solvent; dihalogenation is carried out selectively. The said halides can be used to give meta-phenoxybenzaldehyde by hydrolysis in basic or acidic aqueous media.
