Alkenylation and allylation of alkyl iodides with alkenyl and allyl sulfones, respectively, took place under Pd/photoirradiation system. The initial alkyl radical, derived from a single electron transfer between Pd(0) and RI, underwent the title transformations. Pd(0) was regenerated through a reductive elimination of PhSO2PdI, which is formed by the combination of the sulfonyl radical and the palladium
在Pd /光辐射体系下,烷基碘与烯基和烯丙基砜分别进行烯基化和烯丙基化。由Pd(0)和RI之间的单电子转移获得的初始烷基进行了标题转换。通过还原消除PhSO 2 PdI来再生Pd(0),PhSO 2 PdI是由磺酰基和钯自由基的组合形成的。添加水是有效的,大概是通过PhSO 2 I的水解来推动平衡。
