METHOD FOR PREPARING BROMOMETHYL-BIPHENYL DERIVATIVES
The invention concerns a method for preparing 4'-bromomethyl-biphenyl derivatives of general formula (I) in which R is as defined in Claim 1, characterised in that it consists in reacting in a biphasic medium and under the effect of light irradiation, a bromination agent selected among bromine, N-bromoacetamide, N-bromophtalimide, N-bromomaleimide, a N-bromosulphonamide, N-bromosuccinimide, 1,3-dibromo-5,5-dimehtylhydantoin and an alkaline metal bromhydric/bromate acid system with a biphenyl derivative of general formula (II) in which R has the same meaning as above, thereby obtaining the desired compound.
