| 摘要 |
<p>An ethylenically-unsaturated aliphatic hydrocarbon is coupled with an aromatic hydrocarbon having an active hydrogen on a saturated alpha-carbon in the presence of a supported alkali metal as a catalyst and 10-100 mol %, based on the amount of the alkali metal catalyst, of an oxide of sodium or potassium as a co-catalyst. In preferred embodiments of the invention, the ethylenically-unsaturated aliphatic hydrocarbon is an alkene of 2-20 carbons, such as ethene or propene; the active hydrogen-containing aromatic hydrocarbon is an alkylbenzene, such as toluene; the alkali metal is potassium or a potassium alloy; and the co-catalyst is sodium oxide.</p> |
