The reaction of p-TC6H4+ (I), generated from the nuclear β-decay of p-T2C6H4, with CH4, C2H6, or C3H8 (at 10-100 torr partial pressures) gives the corresponding TC6H4R (R = Me, Et, Pr, Me2CH). The reactions of I show that it is very reactive towards pure σ-type substrates and that these reactions are C-H bond regioselective. The stability of TC6H5R+, intermediates in the reactions of I, and their fragmentation- and isomerization-mechanism are discussed. These studies are compared to those from ion-cyclotron mass spectral studies at 10-5 torr. The effect of NH3 or MeOH on the reactions of I with alkanes is also discussed.

Abstract
The reaction of p-TC6H4+ (I), generated from the nuclear β-decay of p-T2C6H4, with CH4, C2H6, or C3H8 (at 10-100 torr partial pressures) gives the corresponding TC6H4R (R = Me, Et, Pr, Me2CH). The reactions of I show that it is very reactive towards pure σ-type substrates and that these reactions are C-H bond regioselective. The stability of TC6H5R+, intermediates in the reactions of I, and their fragmentation- and isomerization-mechanism are discussed. These studies are compared to those from ion-cyclotron mass spectral studies at 10-5 torr. The effect of NH3 or MeOH on the reactions of I with alkanes is also discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
