DEFINITION

Classification: 554/143

(under subclass 141) Processes wherein conversion of a functional group occurs during the course of hydrogenation (addition of hydrogen).

(1) Note. Some examples of hydrogenolysis are conversion of an oxo carbonyl group to hydroxy; of a hydroxy group to hydrogen, etc.
