DEFINITION

Classification: 987/160

Contains the structure Q-(C)-P(=X)(X)(X-C) where Q is a moiety containing an atom other than C or H (9/40A; 9/40A1; 9/40A1+U9; 9/40B):

(under subclass 147) Subject matter wherein the P compound contains the structure (Q-C)-P(=X) (X)(X-C) and wherein Q contains an atom other than C or H.

(1) Note. The atom which is other than C or H may or may not be directly bonded to the C atom of the (Q-C)-P group and the linkage to the C atom is not through the P atom.
