Abstract
In the framework of their review of carbocationic initiation of olefin polymerization Gandini and Cheradame have hypothesized that carbocationic blocking and grafting of alkenes in the presence of Friedel-Crafts acids may also proceed by an “onto” mechanism and not by a “from” process suggested by Kennedy et al. A wide battery of facts and recently generated information substantiate the blocking and grafting from mechanisms and refute Gandini and Cheradame's onto hypothesis.
