DEFINITION

Classification: 987/154

Contains the structure aryl-(C)n-P(=X)(X)(X-C) where n is at least one (9/40A7; 9/40A7+P):

(under subclass 147) Subject matter wherein the P compound contains the structure aryl-(C)n-P(=X)(X)(X-C) wherein n is at least one and the aryl group is bonded indirectly to the P group through a chain of only C atoms.
