DEFINITION

Classification: 987/153

Contains the structure (X=C*)-P(=X)(X)(X-C) or (cyano*)-P(=X)(X)(X-C) where * indicates a direct bond of the C of the C=X group or of the C atom of the cyano group directly to the P atom (9/40A9; 9/40A9+Q):

(under subclass 147) Subject matter wherein the P compound contains the structure (X=C)-P (=X) (X) (X-C) or (N#C)-P(=X) (X) (X-C) where X is a chalcogen atom and N#C indicates a triple bond between the N and C atoms.
