The title compounds are prepared in a process comprising contacting an alkali metal or alkaline earth metal salt of a tetra- or pentahalophenol with a vinylbenzyl chloride in a liquid, aqueous solvent containing from about 68 to about 90 weight percent of a C1 or C2 alkanol in a remaining amount of water. The contact of the aforementioned reactants occurs at a pH from about 7 to about 11 and at a temperature less than about 65 DEG C. As an example, sodium pentachlorophenoxide can be reacted with vinylbenzyl chloride by this process in an aqueous methanol solvent (with about 20 weight percent water) to yield about 90 percent pentachlorophenylvinylbenzyl ether, based on vinylbenzyl chloride. |
