DEFINITION

Classification: 987/193

Contains the structure P-(N-*acyl), P-(N-*Z) or (N-*cyano) where Z is an atom other than C or H and * indicates a direct bond to the adjacent N atom (9/24C9; 9/24C9+M; 9/24C9+Q; 9/24C9+U; 9/24C9+W):

(under subclass 187) Subject matter wherein the phosphorus compound contains the structure: (a) P-(N-acyl) where a carbon of the acyl group is directly bonded to the N atom, or (b) P-(N-Z) where Z is an atom other than C or H and is directly bonded by a covalent bond to the N atom, or (c) P-(N-C#N) where the N atom is directly bonded to the P atom and C#N indicates a triple bond between the C and N atoms.
