The intermolecular hydroamination of 1,3-cyclohexadiene with aniline using zeolite catalysts was investigated. The reaction mechanism and the influence of amine basicity on the rate of reaction were studied. Zeolite H-BEA was the most active catalyst, whereas the incorporation of Zn2+ (Zn/H-BEA) led to decreasing catalytic activity, indicating that the reaction is catalyzed by Bronsted acid sites. Subtle shape selective effects determine the reactivity and selectivity of the zeolites.

Reactions of aryl azides (1) with cyclohexene gave 3-(arylamino)cyclohexenes (2) and trans-1-chloro-2-(arylamino)cyclohexanes (3), whereas that of (1) with cycloheptene or cis-cyclo-octene afforded novel aziridines, 8-aryl-8-azabicyclooctanes (4), or 9-aryl-9-azabicyclononanes (5), respectively.The reaction of phenyl azide (1a) with cis-4-methylpent-2-ene yielded 3-anilino-2-chloro-4-methylpentane (10), but that with the trans-alkene gave 4-anilino-2-methylpent-2-ene (7) and 3-anilino-4-methylpent-1-ene (8).The similar reaction of (1) with 3-trimethylsilylcyclohexene or 3-trimethylsilyl-cis-cyclo-octene produced only (2) or 3-(arylamino)-cis-cyclo-octenes (2').The formation of the aziridines or the ring-opened products was explained by a mechanism via an aziridinium-AlCl3 complex formed from an azide-AlCl3 complex.
