摘要

The radical cations of 2, 2-dialkyl-and 2-alkyl-2-aryl-l, 3-dioxolanes, when generated in solution by photoinduced electron transfer to 1, 2, 4, 5-benzenetetracarbonitrile (TCB), fragment to yield alkyl radicals. These are trapped by electron-withdrawing substituted alkenes (acrylonitrile, methyl acrylate, methyl vinyl ketone, as well as dimethyl maleate and fumarate). The radicals thus formed are either reduced by the TCB radical anion or add to ...
