-CYCLOADDITIONS OF ALKENES WITH THE TRIPHENYLALLENYL CATION
Mayr, Herbert,Baeuml, Englbert
, p. 1127 - 1130 (2007/10/02)
The triphenylallenyl cation (8), generated from triphenylpropynol (7) and FSO3H, reacts with alkenes to give the allyl cations 12, which may be deprotonated to yield the methylenecyclobutenes 14.Alternatively, 12 can be converted into the 2-vinyl-indenes
