Cyclopropyl derivatives have been prepared with good yields by transition-metal catalysed electroreductive coupling of activated olefins and unactivated gem-dibromo compounds. This electrolysis is characterized by the use of a Fe/Ni catalyst system, acetonitrile as the solvent and a catalytic amount of triphenylphosphine as ligand. This procedure is a good alternative to the classical preparations of cyclopropyl derivatives from activated olefins (Simmons-Smith reaction, 1,3-dipolar addition of diazomethane, 1,4-addition of phosphorus and sulfur ylides).

As representatives of a novel class of carboxylic nucleoside analogues (+/-)-cis-, (-)-cis and (+/-)-trans 9-(2-hydroxymethylcyclopropyl)-adenine (= -methanol) were synthesized from the corresponding dialkyl 1,2-cyclopropane dicarboxylates.
Synthesis of Dimethyl 1,2-Cycloalkanedicarboxylates by Electrochemical Cyclization of Dimethyl α,α-Dibromoalkanedioates Using a Copper Anode

The electrochemical cyclization of dimethyl α,α'-dibromoalkanedioates by making use of a platinum cathode and a copper anode in the presence of sodium iodide gave three- to six-membered dimethyl 1,2-cycloalkanedicarboxylates in good yields.
