Abstract: γ-Hydroxycarboxylic esters and γ-lactones which are suitable as flavors can be prepared by electrochemical reductive cross-coupling of α,β-unsaturated esters with carbonyl compounds in an undivided electrolysis cell having a cathode composed of lead, lead alloys, cadmium, cadmium alloys, mercury, steel, glassy carbon or boron-doped diamonds and a basic aqueous electrolyte comprising an electrolyte salt which suppresses the cathodic formation of hydrogen.

Abstract: The invention relates to a process for coating plastics or plastic surfaces with metals, especially plastics composed of acrylonitrile/butadiene/styrene copolymers (ABS) and composed of mixtures of these copolymers with other plastics (e.g. ABS blends), wherein the process comprises the pretreatment of the plastic surfaces with a composition C (etch solution) comprising at least two different ionic liquids IL1 and IL2.
