DEFINITION
Classification: 585/364
By condensive ring expansion, e.g., "olefin dismutation", etc.:
(under subclass 350) Subject matter wherein the alicyclic compound is synthesized from a feedstock molecule, usually a cycloolefin, having fewer carbons in its ring than the product molecule, the carbons added to the ring being contributed by another molecule.
(1) Note. The final product may incorporate all of the carbon atoms of the feedstock molecules (polymerization) or only part of the carbon atoms of one feedstock (disproportionation).
SEE OR SEARCH THIS CLASS, SUBCLASS:
362, for cycloolefin dimerization in which the product has plural rings.
643+, for olefin disproportionation reactions aimed at the production of acyclic monoolefins. Many of the catalysts used in such reactions are disclosed as being useful in the reactions of this subclass (364).
