Abstract

The isotope exchange method was employed to investigate the catalytic mechanism of ionic liquid in alkylation of benzenes with olefins It is proposed that alkylation was induced by the Lewis acid AlCl3 which attracted π electrons of 1dodecene to shift toward 1carbon thus forming a carbonium ion The carbonium ion further reacted with benzenes to form a complex Due to unstabilit of the complex a deuterated ring proton was transferred into an electronegative 1carbon of the side chain to substitute for the AlCl3 accordingly 2phenyldodecane was generated
