DEFINITION

Classification: 987/141

Contains the structure (C)-P(=X) (X) (N) (N-*acyl), (C)-P(=X) (X)(N-Z) or (C)-P(=X) (X)(N-*cyano) where Z is an atom other than C or H and * indicates a direct bond to the adjacent N atom (9/44C9; 9/44C9+Q; 9/449+ U):

(under subclass 140) Subject matter wherein the P compound contains the structure (C)-P(=X)(X)( N-acyl); (C)-P(=X)(X)(N-Z) or (C)-P)(=X)(X)(N-cyano) wherein Z is an atom other than C or H and X is chalcogen.

(1) Note. The C of the acyl group, the atom other than C or H, and the C of the cyano radical are all bonded directly to the nitrogen atom.
