CONCERTED AND STEPWISE CYCLOADDITIONS OF THE TRIPHENYLALLENYL CATION WITH CYCLOPENTADIENE

Mayr, Herbert,Baeuml, Englbert

, p. 357 - 360 (1983)

The triphenylallenyl cation (5), generated in situ under different conditions, reacts with cyclopentadiene via allyl cations 7 and 9.The exclusive formation of 7 from 12 and FSO3H proves a concerted cycloaddition leading to 9 and suggests a stepwise cycloaddition reaction to give 7.
