DEFINITION

Classification: 987/30

PHOSPHORUS CONTAINING COMPOUNDS (9/02; 9/06):

(under the class definition) Subject matter drawn to organic

compounds wherein phosphorus is bonded either directly to a carbon or is indirectly bonded to carbon only through non-ionic bonding.

(1) Note. In those subclasses which do not recite a valence requirement, the P atom can be in any valence state.

(2) Note. Many of the subclasses are presented in a structural formula recited format. The requirement for this and the indented subclasses and in the absence to the contrary is that a single moiety must exist in the compound having the required structure. It is permissible that the compound contain multiple moieties of the structure, although in most instances this does not occur or special provision has been made for those concepts by the creation of subclasses requiring that feature.

(3) Note. The following rules apply to the use of structural formulas or symbols in the schedule or definitions. A structure such as:

(a)

Hal-P-N or (Hal)-P-(N) indicates a direct bond between the Hal and the P atom and a direct bond between the N atom and the P atom. Other atoms may be bonded to the P and N atoms. Atoms represented as being adjacent atoms to each other by a hyphen indicates a direct bond between those atoms. A hyphen may represent a single, double, or triple bond.

(b) P=N or P(=N) indicates a direct double bond between the P atom and the N atom. Other atoms may be bonded to the P and N atoms.

(c)

C=X or (C=X) represents a double bond between a carbon atom and a chalcogen atom and where presented in a structure indicates a direct bond between the C and the P atom, i.e., P-(C=X) indicates that a direct bond exists between the C atom of the (C=X) group and the P atom.

(d)

A single atom between parentheses (any atom) indicates a direct, e.g., single, double, etc., bond between that atom and a phosphorus atom, e.g., P-(O) indicates that the bond between the P and the oxygen atom is direct and not through another atom, and can be a single or double bond, and P-(C) indicates a direct bond between P and C and the C can be of any valence, etc.

(e)

A single atom between parentheses (=any atom) indicates a

direct double bond between that atom and a phosphorus atom, i.e., P-(=O) indicates that the bond between the P atom and the oxygen atom is direct and must be a double bond.

(f)

A moiety between parentheses indicates a direct bond between the moiety and the P. If the moiety is (X-and any other atom) where S is chalcogen, the direct bond is always between the chalcogen and the P atom, unless there exists a double bond between the X atom and the other required atom, i.e., C=X in which case the direct bond is between the C and the P atom.

(g)

Chemical moieties shown without parenthesis with the exception of moieties shown between quotation marks "--" (see (h) below) cannot be bonded directly to the required P atom. Furthermore, they may or may not be directly bonded to the adjacent indicated atom. (h)

Chemical moieties shown between quotation marks "--" indicates that an atom of the group, e.g., "ethylenic group," indicates that a carbon of the ethylenic group can be directly or indirectly bonded to a P atom and "carbocyclic ring" indicates that a carbon atom of the carbocyclic ring can be directly or indirectly bonded to the P atom, etc.

(i)

The term "Q" indicates a moiety containing an atom other than C or H. The particular atom that is other than C or H may or may not be bonded directly to the adjacent atom shown. The bonding to the adjacent atom shown cannot be through a phosphorus atom and requires a bond other than ionic.

(j)

X used throughout the schedule and definitions is limited to chalcogen, i.e., Oxygen (O), Sulfur (S), Selenium (Se), and Tellurium (Te). For ease of readability, in many instances, the chemical symbols for these elements have been used.

(k)

Phosphorus and its chemical symbol (P), carbon and its chemical symbol (C), nitrogen and its chemical symbol (N), and hydrogen and its chemical symbol (H) have been used interchangeably throughout the schedule and definitions.

(l)

Halogen or its abbreviated form (Hal) has been used throughout the schedule or definitions to indicate the presence of fluorine, chlorine, bromine, iodine, or astatine

atoms.

(m) The term "Z" indicates an atom other than C or H and requires a direct non-ionic bond between the particular atom that qualifies as Z and the adjacent atom indicated. The term is meant to exclude classification on the inorganic portion of an organic phosphorus containing compound. See (q) below.

(n)

Chemical moieties shown within parentheses and an asterisk (*). (1) (Aryl*) indicates that a carbon of the aryl ring is bonded to the adjacent indicated atom shown. (2) (Carbocyclic*) indicates a ring atom of the carbocyclic is directly bonded to the adjacent indicated atom shown. (3) (Ethylenic*) indicates a carbon of the unsaturated group (double or triple bond) is directly bonded to the adjacent atom shown. (4) (Cyano*) indicates a direct bond between the carbon of the cyano group and the adjacent atom shown. (5) (Acyl*) indicates a direct bond between the carbon of the acyl group and the adjacent group shown.

(o)

A moiety interposed between quotation marks "--" indicates that it is alternative as to whether the named group is directly or indirectly bonded to the P atom.

(p)

Bonded directly or directly bonded indicates a non-ionic bond between the two adjacent required atoms or moieties.

(q)

Indirectly bonded or bonded indirectly indicates a nondirect, non-ionic, linkage between nonadjacent atoms or moieties. The terms are used to exclude classification on the inorganic portion of a salt. When a compound is composed of both an organic cation and an organic anion, then classification on both of the organic moieties is appropriate.

(4) Note. Organic acid salts, alcoholates, phenates, chelates, or mercaptides are classified on the basis of the organic portion of the compound that contains the phosphorus atom. If both the anion and cation are organic, the entire molecule is classified.
