DEFINITION

Classification: 987/167

Contains the structure "ethylenic group" -P(=X) (X) (X) where "--" indicates that a carbon atom of the ethylenic group may or may not be directly bonded to the P atom (9/38A2):

(under subclass 146) Subject matter wherein the C atom bonded directly to the P atom is part of an ethylenic group, or is bonded directly or indirectly to an ethylenic group and wherein the linkage is not through the P atom.

(1) Note. An ethylenic group is defined as a double or triple bond between adjacent acyclic carbon atoms.
