The r-radiolysis of homogeneous solid solutions of SF6 and NzO in cyclohexane has been examined at 77 "K. With SF6, yields of the major products, hydrogen, bicyclohexyl, and cyclohexene, were all reduced, and no large yields of other products were observed. Thus, since SF6 reduces hydrogen yields by capturing electrons, combination of the SF6 anion and cyclohexane cation does not lead to bond breaking. Experimental evidence suggests that the ratio of disproportionation to combination of cyclohexyl radicals in solid cyclohexane atWith N 2 0 , hydrogen yields are decreased to 3.5 G units, but large yields of cyclohexene, bicyclohexyl, and cyclohexanol (4.7, 2.0, and 1.0 G units respectively) are produced. Thus combination of 0-and the cyclohexane cation leads to a great deal of bond breaking. The yields are explained by a mechanism similar to Dyne's mechanism for the radiolysis of hydrocarbons. It was, however, necessary to assume that excited states of cyclohexane formed directly behave differently from those formed by electroncation combination.Canadian Journal of Chemistry, 46, 89 (1968) lrntroduction other rather than abstract hydrogen from the Charge separation is important in the radial-ll~drocarbon at low temperatures.

“…Cyclohexyl radicals have also been observed to add to the double bond of cyclohexene to initiate a radical chain. 45,46 The radical chain initiated by a cyclohexyl-t radical would eventually undergo termination and be monitored as polymer-t. The yield of polymer-t also increased with increasing amounts of added moderator.…”

Reactions with Cyclohexene and Alkenes 347 tion. The experimental data in Figure 11 show that tmax is reduced to one-half, from 70 to 35 Msec, upon increasing the monomer concentration from 0.29 to 0.54 M, as predicted by eq 12. This result indicates that the decay of the dimer radical cation is due to the trimerization reaction, eq 10. These dimerization and trimerization reactions are considered to be the initial step of the photoinduced cationic polymerization.
