DEFINITION

Classification: 987/156

Contains the structure (aryl*)-P(=X)(X)(X-C) * indicates a direct bond between a carbon of the aryl ring and the P atom (9/40A4):

(under subclass 147) Subject matter wherein the P compound contains the structure aryl-P(=X) (X)(X-C) wherein one of the C atoms of the aryl ring is bonded directly to the P atom.

SEE OR SEARCH THIS CLASS, SUBCLASS:

157, for an aryl containing moiety bonded indirectly to the carbon of the C-P group and wherein the indirect linkage to the C atom is not through the P atom.
