ABSTRACT:
An alkene selected from ethene, propene, and mixtures thereof is coupled with an aromatic hydrocarbon having an active hydrogen on a saturated alpha-carbon in the presence of a supported potassium or potassium alloy as a catalyst and an alkaline earth metal oxide as a co-catalyst. In a preferred embodiment of the invention, the active hydrogen-containing aromatic hydrocarbon is an alkylbenzene, such as toluene.
