Solvent-free, one-pot synthesis of pentasubstituted cyclopropanes in the presence of BrCN and EtONa by milling

A solvent-free, one-pot process for the preparation of pentasubstituted 3-arylcyclopropane-1,1,2,2-tetracarbonitriles in the presence of solid sodium ethoxide by milling was achieved. The one-pot reaction of aromatic aldehydes and dialdehydes with malonon

Cyclopropanation of Electron-deficient Alkenes and Wideqvist-type Synthesis of Cyclopropanes mediated by Indium Metal

Cyclopropanation of electron-deficient alkenes and Wideqvist-type transformation of carbonyl compounds to cyclopropanes have been achieved by the action of active methylene dibromides and metallic indium.
