Abstract
Kolbe electrosynthesis, at low current densities, of 1,2-diphenylethane and 1,2-di(bicyclo[2.2.1]heptan-2-yl)ethane with 77 and 72% yields, respectively, is described.

a Number of electrons involved per molecule of phenylacetic acid.
b Total volume of electrolyte solution was 25 cm3.
c Total volume of electrolyte solution was 50 cm3.
Note. η m = [obtained mass of dimer (g) / theoretical mass of dimer (g)] × 100; η c = [moles of product obtained by a charge c / theoretical moles of product obtained by a charge c] × 100.
