WebUsing a high direct current and a platinum electrode, the traditional reaction oxidises the starting material. The two molecules decarboxylate, emitting carbon dioxide and producing radicals that dimerise to form a new carbon–carbon bond. However, the harsh conditions usually oxidise other functional groups too, destroying the intended product.
