Abstract
The main fragmentation pathway of vinyl triflates in mass spectra invo lves the loss of CF3SO2., followed by the loss of olefin and/or CO. Th e loss of TfOH takes place with fragmentation of a vinylic C-H bond. T fOH-2+ ions are formed via regiospecific double hydrogen transfer from five- and six-membered cyclic triflates.
