DEFINITION

Classification: 987/120

Pentavalent P compound having the structure (X=C*)-P(=X) or (cyano*)-P(=X) where X is chalcogen, * indicates a direct bond of the C of the C=X group or of the C of the cyano group directly to the P atom, and the other atoms bonded directly to the P atom are either carbon or hydrogen (9/53A9; 9/53P; 9/53Y):

(under subclass 116) Subject matter wherein the P compound contains the structure (B)-P(=X) (C)(C); (B)-P(=X) (C)(H); (B)-P(=X) (H)(H) where B is the group X=C or N#C, the carbon atom of the B group is directly bonded to the P atom and X is chalcogen and N#C indicates a triple bond between the N and C atoms.
