Abstract

The preparation of 1, 1-disubstituted and monosubstituted cyclopropanes 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.
