DEFINITION

Classification: 558/361

(under subclass 360) Processes wherein the nitrile reactant contains carbon to carbon unsaturation and is acyclic.

(1) Note. An amalgam is an alloy of mercury.

(2) Note. The art terms often used for the type reactions provided for herein are "reductive dimerization" or "hydrodimerization."
