11. The reaction proceeds though a single electron transfer process, involving a carbocation . 12. Driving force is the stabilization of said carbocation by the beta-silicon effect. 13. This usually occurs only when that carbocation is an allylic or a benzyllic carbocation. 14. This usually occurs only when that carbocation is an allylic or a benzyllic carbocation . 15. I assume in general the longer-chain primary carbocation would be more stable? 16. Well anyway, why isn't the C + carbocation resonance contributor shown? 17. Will it decompose onto ether + carbocation anyway? 18. George Olah of the United States won last year for his contributions to carbocation chemistry. 19. In the first step, the leaving group departs, forming a carbocation C +. 20. For instance in the following alkyl benzenesulfonate the alkene is able to delocalise the carbocation .
