Previous studies of phenyl substituted tropylium3 and cyclopropenylium4 cations have indicated relatively little interaction of the phenyl substituent (s) with the central kharged ring In the ground state. In a few cases %,c,e phenyl substitution was reported to exert an apparent destabilizing effec
The a-alkynyl vinyl triflates (2) are synthesized and the solvolyses reactions studied in different solvents. The solvolysis products and kinetic data indicate, that the hitherto unknown triple bond stabilized vinyl cation 2a e, 2b is formed as an intermediate. --
