Photo-excited arenes have been found to initiate a substitution reaction in which the sulfonyloxy group of α-sulfonyloxyketones is displaced, and the corresponding β-arylketones are formed. Evidence is presented that the electronically excited arene need not be involved directly in the substitution step. It would seem to be more likely that upon interaction with the sulfonyloxyketone a reactive species
已经发现光激发的
芳烃引发取代反应,其中α-磺酰氧基酮的磺酰氧基被置换,并形成相应的β-芳基酮。证据表明,电子激发的
芳烃不需要直接参与取代步骤。在与磺酰氧基酮相互作用时,似乎更有可能产生衍生自后者的反应性物质,其能够进行芳族取代。
