DEFINITION

Classification: 987/148

Contains the structure (C)-P (=X) (X) (X-*acyl), (C)-P(=X) (X-C) (X-*Z), or (C)-P (=X) (X) (X-*cyano) where Z is an atom other than C or H and * indicates a direct bond to the adjacent X atom (9/40C9; 9/40C9+Q; 9/40C9 + U):

(under subclass 147) Subject matter wherein the P compound contains the structure (C)-P(=X) (X) (X-acyl) (C)-P(=X) (X) (C-Z), or (C)-P(=X) (X) (X-cyano) wherein Z is an atom other than C or H.

(1) Note. 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 X (chalcogen atom).
