  Radical 3-exo-tet cyclization of 1,3-dihalopropanes with SmI2 to form cyclopropanes

  摘要：

  The preparation of 1,1-disubstituted and monosubstituted cycloproparres from corresponding 2,2-disubstituted and 2-monosubstituted 1,3-dihalopropanes, respectively, with SMI2 in THF was efficiently carried out. The reaction mechanism was proposed to proceed in a radical 3-exo-tet manner based on Baldwin's rule. (c) 2008 Elsevier Ltd. All rights reserved.

  The 3-exo-tet cyclization of 2,2-disubstituted 1,3-dihalopropanes with In powder in THF solution of 20% H2O, dioxane solution of 20% H2O, and ionic liquids, such as [bmim]Br, [bmim]Cl, and [bmin]BF4, respectively, was efficiently carried out to form the corresponding 1,1-disubstituted cyclopropanes in good yields. The cyclopropanation of 2,2-disubstituted 1,3-dihalopropanes with In powder in ionic liquids, such as [bmim]Br, [bmim]Cl, and [bmin]BF4, was markedly accelerated compared with that in a THF solution of 20% H2O and a dioxane solution of 20% H2O. The mechanism was proposed to involve the radical 3-exo-tet cyclization of the formed 3-halopropyl radical. (C) 2009 Elsevier Ltd. All rights reserved.
