DEFINITION

Classification: 534/739

(under subclass 573) Compounds in which an azo group is bonded directly to an acyclic carbon, which carbon is additionally bonded directly to two acyclic carbons, each of which is double or triple bonded to an atom.

(1) Note. The term "reactive methylene" is used in reference to the acyclic carbon to which azo group and other two carbons are bonded.

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