Abstract

Abstract: Gas-phase isomerization of cyclohexylium ion (l), obtained via protonation of cyclohexene and of bicyclo [3.1. O] hexane and via hydride-ion abstraction from cyclohexane by C, H5+(n= 1, 2) and by s-C3H,+ ions, has been investigated by a radiolytic technique in CHI and C3Hs in the pressure range from 106 to 1480 Torr. Temperature- dependence studies in the temperature interval from 310 to 353 K have provided the ...
