Pure organic compounds containing one or more metals whereby at least one metal is carbon bound, and their preparation.

Pure organic compounds containing one or more metals, without metal-carbon bonds, that can be represented by the formula: (L1)n-Metal-(L2)m (n>0 and m>0); L1 and L2 are different metal-bound moieties, and their preparation.

Relationship between large subject matter areas

Polymers: Linear siloxanes are classified in C07F when they have up to six -(Si-O)- repeating units. Linear siloxanes having more than six -(Si-O)- repeating units are classified in C08G 77/00.Siloxanes having endocyclic -(Si-O)- units are classified in C07F 7/21.

Metal salts and metal chelates: only metal-containing compounds having a metal carbon bond or wherein the metal is attached to at least two different ligands are classified in C07F. Salts, chelates, alcoholates (except Ti/Zr), phenates and the like involving a single ligand are classified as the parent compound

Salts, adducts or complexes formed between two or more organic compounds: these are classified according to all compounds forming the salts, adducts or complexes.

Mixtures, solutions: mixtures, solutions and the like of known compounds are not classified in C07F, but only according to their use

Special rules of classification within this subclass

In the absence of an indication to the contrary, the Periodic System of chemical elements referred to is the one with 8 groups as represented in the table below. For example, group C07F 3/00 "Compounds containing elements of the 2nd Group of the Periodic System" refers to the elements of columns IIA and IIB.

- In subclasses C07C-C07K and within each of theses subclasses, in the absence of an indication to the contrary, a compound is classified in the last appropriate place.

- Remark about classifying a document relating to more than one of the metals for which individual subgroups have been created: when complete classification would lead to a high number of classification symbols (e.g. the compounds to be classified fall into -nearly- all of the subgroups under one and the same hierarchically higher group) classification is made under the said higher group only. Otherwise, classification is made under all appropriate subgroups, and not under the said higher group.

- In this subclass, "preparation" covers purification, separation, stabilisation or use of additives, unless a separate place is provided therefore.

- Chemical compounds and their preparation are classified in the groups for the type of compound prepared.

- If of interest, e.g. if the process relates to the preparation of known compounds and involves novel process/preparation features, the processes of preparation are also classified in the groups for the types of reaction employed. If no specific preparation class is foreseen, the preparation is classified in the class for the product obtained by the process.

- Compounds obtained by the claimed process are -as a rule- not classified (rationale is that a compound is not novel because it has been prepared by a novel process). However, if the product obtained by the process according to the invention can be considered novel, then that product should be classified (this would apply to products that can best be described by a product-by-process definition).

- General processes for the preparation of a class of compounds falling into more than one main group are classified in the groups for the processes employed, when such groups exist.

- In ECLA, there have been created classes -------/00B to classify metal-containing compounds that do not have a metal-carbon bond but that can be represented by the formula: (L1)n-Metal-(L2)m (n>0 and m>0); L1 and L2 are different metal-bound moieties, and their preparation.

- Salts of a compound, unless specifically provided for, are classified as that compound. Carboxylic acid salts are classified as the carboxylic acid, e.g. sodium malonate is classified as malonic acid (in C07C 55/08). A mercaptide is classified as the mercaptan. Metal chelates are dealt with in the same way. Metal alcoholates and metal phenates are classified in subclass C07C and not in subclass C07F.

- Salts, adducts or complexes formed between two or more organic compounds are classified according to all compounds forming the salts, adducts or complexes.

- Compounds containing unusual isotopes are classified in C07F and C07B59/00 and get the code M07M5/00:00

- C07F compounds on a support get -in addition to the C07F class- the code M07M11/00:00

- C07F compounds containing unusual isotopes are classified in C07F and in C07B 59/00.

In addition to the classification in C07F, a document has to be forwarded for classification to the field relating to the use or application of the compound, entity comprising the compounds (if such use or application or entity is claimed or specifically described). As an exception, the medical use (A61K 31/00) of novel compounds is not forwarded for classification. Likewise, documents relating to apparatus used in processes have to be forwarded to the appropriate fields.
