The inside cover picture, provided by Pavel Nosik, Sergey Ryabukhin, Dmitriy Volochnyuk, and Oleksandr Grygorenko illustrates difluorocyclopropanation of electron‐deficient alkenes with CF₃SiMe₃–NaI system using the “slow addition” protocol. The method is effective for various α,β‐unsaturated esters, which opens an access to difluorocyclopropyl‐substituted carboxylic acids on a multigram scale.

CF ₃ SiMe ₃ -NaI系统的无过渡金属宝石-烯烃的二氟环丙烷化：缺电子衬底的配方

所述内封面图片，由帕维尔Nosik，塞吉Ryabukhin，德米特里Volochnyuk和阿列克Grygorenko提供示出了与CF缺电子烯烃的difluorocyclopropanation ₃森达₃使用“缓慢加入”协议-NaI系统。该方法对各种α，β-不饱和酯均有效，从而以克数为单位打开了二氟环丙基取代的羧酸的途径。Web Design Studio“ ZORELiT”的背景图稿。细节可以在上页面的全部论文中找到XXXX-XXXX（PS Nosik，SV Ryabukhin，OO Grygorenko，DM Volochnyuk，进阶合成器CATAL。 。2018，360，为xxxx-xxxx; DOI：10.1002 / adsc.201801006）。
