  A benchtop stable, bifunctional reagent for the redox-neutral cyclopropanation of olefins has been developed. Triethylammonium bis(catecholato)iodomethylsilicate can be readily prepared on multigram scale. Using this reagent in combination with an organic photocatalyst and visible light, cyclopropanation of an array of olefins, including trifluoromethyl- and pinacolatoboryl-substituted alkenes, can

• Nickel-Catalyzed Favorskii-Type Rearrangement of Cyclobutanone Oxime Esters to Cyclopropanecarbonitriles
  作者：Ping Fang、Tian-Sheng Mei、Bin Shuai

  DOI：10.1055/s-0039-1690872

  日期：2021.10

  A nickel-catalyzed base-promoted rearrangement of cyclo­butanone oxime esters to cyclopropanecarbonitriles was developed. The ring opening of cyclobutanone oxime esters occurs at the sterically less hindered side. A base-promoted nickelacyclobutane intermediate, formed in situ, is assumed to be involved in the formation of the product.

• The diastereoselective synthesis of 2,3-diaryl-3-cyano-substituted pyrrolidines via the MgI2 mediated ring expansion of aryl cyclopropyl nitriles
  作者：Darren Stead

  DOI：10.1016/j.tetlet.2020.152325

  日期：2020.9

  reaction of aryl substituted cyclopropyl nitriles with tosyl aldimines to give 2,3-diaryl-3-cyano-substituted pyrrolidines has been demonstrated. In all cases, the trans-diastereoisomer was determined to be the major product. The overall yield and diastereoselectivity of the reaction showed some sensitivity to the electronic and steric demands of the aryl cyclopropyl nitriles and the tosyl aldimines
