DEFINITION

Classification: 987/211

Containing the structure P-(X-*acyl), P-(X-*Z) or P-(X-*cyano) wherein Z is other than C, H, or a salt forming moiety and * indicates a direct bond to the adjacent X atom (9/165A9; 9/165A9+M; 9/165A9+Q; 9/165A9+U):

(under subclass 209) Subject matter wherein the P compound contains the structure: (a) P-(X-acyl) or (b) P-X-(C#N) X is a chalcogen atom and is bonded directly to the P atom and wherein the C of the acyl group and the C of the cyano group are all directly bonded to the X atom and C#N indicates a triple bond between the C and N atoms.
