DEFINITION

Classification: 987/225

Containing the structure P-(O-*acyl), P-(O-*Z) wherein Z is an atom other than C or H, or P-(O-*cyano) where * indicates a direct bond to the adjacent oxygen atom (9/09A9; 9/09A9+Q; 9/09A9+U):

(under subclass 224) Subject matter wherein the P compound contains the structure: (a) P-(O-acyl), or (b) P-(O-Z) where Z is an atom other than C or H, or (c) P-O-(C#N) the oxygen atom is bonded directly to the P atom and wherein the C of the acyl group, the atom other than C or H, and the C of the cyano group are all directly bonded to the oxygen atom and C#N indicates a triple bond between the C and N atoms.
