Abstract: Disclosed is a process for alkylating halogenated and trifluoromethylated benzene compounds. In that process, an alkyl halide is reacted with a benzene compound having two or three substituents selected from the group consisting of the halogens and the trifluoromethyl group, and also having a hydrogen atom whose two ortho positions are occupied by two of the said substituents. The reaction is carried out in the presence of at least one alkali metal amide and at least one agent that complexes with the cation of the alkali metal amide.

Abstract: An improved elastomeric composition comprising an elastomer (e.g. a natural or synthetic rubber), a filler, and a coupling agent for coupling the elastomer to the filler is provided wherein the coupling agent comprises at least one silane and at least one succinimide. The filler preferably comprises a silica and the succinimide preferably is an alkenyl succinimide, especially an alkenyl succinimide which is the condensation product of a polyamine with an alkenyl succinic anhydride, the alkenyl portion of which has 3 to 100 carbon atoms. The use of silane and succinimide for coupling provides elastomer/filler compositions having highly desirable dynamic and static properties at a more acceptable price and odor level than possible using the silane alone as coupling agent.
