Photochemistry, of carbonium ions

However, with the advent of the superacid solvents, a multitude of long-lived stable carbonium ions have been made available for extended study. Clearly, then, the door is open to quantum 5ueld determinations, kinetic treatment, studies on the effects of various solvents and sensitizers and quenching experiments (compare the very recent study by Bethell and Clare, 1972). In short, the photochemistry of carbonium ions is still in its infancy and there is a wealth of information yet to be gained.

Interest in aromatic chemistry continues at the same high level as in recent years. Substitution and cyclization processes are two areas which have attracted considerable attention over the past year. Pertinent here, as elsewhere in this volume, are the reviews on photochemistry with circularly polarized light by Buchardt,1 and the photochemistry of carbonium ions by Cabell-Whiting and Hogeveen.2 Current literature describing light-induced reactions of pyrroles has also been briefly reviewed.8...
