Abstract

A compound containing one or more aralkyl groups substituted in a structure that has two aromatic rings linked to each other directly and which are also bridged by an oxygen or sulphur atom is made by reacting a compound having two aromatic rings linked to each other directly and which are also bridged by an oxygen or sulphur atom with an aralkyl halide. The products are novel, provided that where there are two aralkyl groups, the aralkyl groups are benzyl groups. The aromatic rings linked to each other can be phenyl, diphenylyl, naphthyl or thienyl. The aralkyl group may contain a methylene, ethylene ethylidene, butylene, isobutylene or hexamethylene group. The aromatic ring may also contain substituents such as halogen, alkyl or alkoxy groups. The aralkyl halide may be a chloride or bromide. The reaction temperature is not less than 50 DEG C. and is preferably 100-250 DEG C. Suitable catalysts which may be used if desired are metal or metal salts, such as halides of the Friedel Crafts type, e.g. aluminium chloride and ferric chloride, or copper or cuprous chloride. The product may be a mixture of isomers which can be separated by chromatography or fractional crystallation. Examples describes the preparation of monobenzyl and dibenzyldibenzothiophenes, and monobenzyl and dibenzyldibenzofurans. Specific examples of new compounds are 2- or 4-benzyl-dibenzothiophene; 2,4 - or 2,8 - dibenzyldibenzothiophene; 2,8 - bis - (p-chlorobenzyl)- or 1-(41 - phenylbenzyl) - dibenzothiophene; 2-benzyl- or 3-(p-methyl-benzyl)- or 2,8-dibenzyl-dibenzofuran; 1-phenyl-2-benzyl- or 2-cyclohexyl - 8 -(31 - phenylbenzyl) - dibenzofuran; 1 - phenyl - 2 - benzyl - 8,9 - benzo - dibenzofuran; 2 - ethoxy - 8 - (a -methylbenzyl)-dibenzothiophene and 2,4,8-tris-(a -methylbenzyl) dibenzofuran.
