title: A facile, one-pot synthesis of beta-substituted (Z)-acrylonitriles utilizing an alpha-diaminoboryl carbanion.
abstract: A simple three-step single-pot procedure for Z-stereoselective synthesis of beta-monosubstituted acrylonitriles has been established. The reaction involves olefination of aldehydes with an in situ generated alpha-diaminoboryl carbanion species. Various aromatic and aliphatic aldehydes were smoothly converted into the corresponding (Z)-olefin products (up to 96:4 ratio) in good yields (80-98%).
