THE ELECTROCHEMICAL SYNTHESIS OF CYCLOPROPANES

The reactions of electrochemical cyclotrimerization of C-H acids, as w ell as electrochemical cyclocondensation of C-H acids and carbonyl com pounds into corresponding, functionally substituted cyclopropanes, are found. The general method of electrochemical cyclization of esters of alpha,alpha,omega,omega-alkanetetracarboxylic acids is realized. Unde r the effect of catalytic amounts of alkoxy anions, tetracyanocyclopro panes are quantitatively transformed into corresponding, bicyclic pyrr olines.
