(Diacyloxyiodo)arene was treated with electron-deficient olefins in the presence of hydrogen donor such as 1,4-cyclohexadiene to give the reductive addition products via alkyl radical through the radical decarboxylative pathway in good yields. Moreover, this system was able to generate either alkoxycarbonyl radicals or alkyl radicals with [bis(alkoxyoxalyloxy)iodo]benzene, which was prepared from alcohol
在氢供体例如1,4-环己二烯的存在下,用缺电子烯烃处理(二酰氧基碘)芳烃,以高收率通过自由基脱羧途径通过烷基产生还原性加成产物。此外,根据反应条件,该体系能够通过两步由[双(烷氧基草酰氧基)碘]苯生成烷氧基羰基或烷基,所述[双(烷氧基草酰氧基)碘]苯是由醇,草酰氯和(二乙酰氧基碘)苯制备的。这些自由基还用于与缺电子的烯烃形成CC键。
