Cyclopropanation of Aryl and Styryl Acetonitriles With Selenium‐Based Dielectrophiles
European Journal of Organic Chemistry, Volume 27, Issue 21, June 3, 2024.Base‐promoted cyclopropanations of aryl or styrylacetonitriles with vinyl selenones are described. The formation of the two new C−C bonds proceeds through a Michael addition followed by a cyclization. Such reactions are usually difficult with pronucleophiles not bearing an additional geminal electron‐withdrawing group.
