Abstract
Abstract Infrared spectra from allylbenzene (or 3-phenyl-1-propene) (C 6 H 5 CH 2 CHCH 2 ) adsorbed on zinc oxide were recorded in the region 3800-1000 cm −1 . Dissociative chemisorption of allylbenzene occurs and yields an adsorbed phenylallyl species [C 6 H 5 CHCHCH 2 ] −1 which is characterized by V asym (CCC) = 1560 cm −1 . When allylbenzene is admitted to a zinc oxide disc containing preadsorbed hydrogen, adsorption of the phenylallyl species causes displacement of the latter from the surface. V asym (CCC) of the adsorbed phenylallyl species now appears at 1570 cm −1 . Prior to evacuation an additional physically adsorbed species is observed, tentatively identified as its isomer 1-phenyl-1-propene (C 6 H 5 CHCHCH 3 ), possibly produced by catalytic hydrogen transfer.
