A straightforward synthesis of trityl alcohols in which one of the aryl rings is substituted with a vinyl group is presented. The synthesis of the alcohols involves the direct addition of the Grignard reagent prepared from 4-bromostyrene to substitutedbenzophenones. These compounds are used to incorporate trityl linker groups into polystyrene-based organic synthesis supports. Both non-cross-linked
