DEFINITION

Classification: 585/438

By condensation using metal-containing catalyst:

(under subclass 435) Subject matter wherein the product is formed by joining plural entire hydrocarbon molecules, e.g., "alkenylation", "olefin arylation", etc., and wherein a catalyst is employed which contains a metal in free or combined form.
