DEFINITION

Classification: 987/122

At least one of the carbon atoms bonded to the P atom is not part of an aryl ring and is bonded directly to an aryl ring

or is bonded to an aryl ring through a chain of acyclic carbon atoms (9/53A7):

(under subclass 121) Subject matter wherein at least one of the carbon atoms bonded to the P atom is directly bonded to a carbon atom of an aryl ring or is bonded to an aryl ring through an acyclic chain containing only carbon atoms.
