Abstract
A number of triflates have been shown to undergo clean pseudo-first-order solvolysis reactions in DMSO-d 6 to give products derived from carbocationic intermediates. Thus, t- BuCH (OTf) CO-t-Bu (5) and t-BuCH2OTf (9) react readily in DMSO-d 6 at 25° C to give a rearranged oxosulfonium salts, and subsequent alkene products where methyl migration to the incipient cationic center occurs. t-BuCH (OTf) CO2CH3 (14) gives analogous ...
