Rapid isomerization of pi-complex intermediates results in the formation of multiple isomers of alkyl aromatics during AlCl3-catalyzed reactions between linear olefins and aromatic rings. The authors present results of a kinetic study of reactions between p-xylene, 1-dodecene, and linear tetradecenes. Product distributions are well predicted based on a model of reversible pi-complex isomerization. Surprisingly, no double bond isomerization was observed in the linear olefins: All isomerization occurred in the pi-complexes. Copyright © 2014 John Wiley & Sons, Ltd. |
