The features of these photochemical processes whose chemical outcomes are dependent upon the nature of reactionpathways available to cationdiradical intermediates are discussed. Finally, the photoinduced, diradicalcyclization methodology for transformation of the silicon-containing N-xylylpyrrolinium perchlorates 4 and 6 has been compared to the alternative dipolar pathway promoted by fluoride-induced
