The front cover picture, provided by Saki Maejima, Eiji Yamaguchi, and Akichika Itoh, depicts the utility of inexpensive molecular iodine as the mediator for the straightforward synthesis of lactones. Visible light irradiation to molecular iodine generates iodine radicals which could mediate a C−C/C−O bond‐forming reaction of olefins with carbonyl compounds furnishing polyfunctionalized γ‐butyrolactones. The study offers an interesting way of utilizing visible light and iodine radicals for intermolecular C–C bond‐forming transformations. Details can be found in the communication on pages 3883–3887 (S. Maejima, E. Yamaguchi, A. Itoh, Adv. Synth. Catal. 2017, 359, 3883–3887; DOI 10.1002/adsc.201700809).

封面图片：烯烃与丙二酸酯的分子间串联加成/酯化反应，导致可见光照射下分子碘介导的γ-内酯（Adv。Synth。Catal。22/2017）

前封面图片由前岛崎贵司（Saki Maejima），山口荣治（Eiji Yamaguchi）和伊藤明纪（Akichika Itoh）提供，描绘了廉价分子碘作为内酯直接合成的介体的效用。可见光照射到分子碘上会产生碘自由基，该碘自由基可介导烯烃与羰基化合物的C-C / C-O键形成反应，从而提供多官能化的γ-丁内酯。这项研究提供了一种利用可见光和碘自由基进行分子间C-C键形成转化的有趣方法。细节可以在上3883-3887页（S.前岛，E.山口，A.伊藤，通信中找到。进阶Synth的CATAL。2017，359 ; DOI 10.1002 / adsc.201700809，3883-3887）。
