The cover picture shows a new method to access 1,1‐difluoroolefins, which are important fluoro‐containing organic compounds. The N ‐tosylhydrazones derived from trifluoromethyl ketones react with arylboronates in the presence of Rh(I) catalyst, affording 1,1‐difluoroolefins in moderate yields. This Rh(I)‐catalyzed cross‐coupling reaction is based on migratory insertion of Rh(I) carbene followed by β ‐fluoride elimination. More details are discussed in the article by Wang et al . on page 473–476.
