| titleOfInvention | METHOD FOR PRODUCING A HALOGENATED BENZOPHENONE, THE PRODUCT OBTAINED THEREOF AND THE USE THEREOF |
| abstract | In a new process for the prodn. of a 2-(chloro- or bromo)-4'- (fluoro-, chloro- or bromo)-benzophenone (I), fluoro- chloro- or bromo-benzene (II) is reacted with an approximately equimolar amt. of a 2-(chloro- or bromo) benzoyl halide (III) in the presence of an aluminium halide, then the reaction prod. is hydrolysed and resulting (I) is isolated in the usual manner and opt. purified (where X is F, Cl or Br; and Y is Cl or Br). (I) are useful as intermediates for pharmaceuticals and plant protection agents, esp. fungicidal triphenylmethane derivs. The process can be carried out in the absence of solvents or diluents, thus avoiding the risk of fire or explosion. Yields are good, and (I) are obtd. in good purity. |
