DEFINITION

Classification: 558/357

(under subclass 303) Processes wherein two organic reactants combine in such a way that a carbon of one reactant bonds directly to a carbon of the other reactant.

(1) Note. For processes where the two organic reactants are plural molecules of identical nitrile reactants, see this class, subclasses 360+.

(2) Note. An example of a process provided for herein is: [figure]
