C07B GENERAL METHODS OF ORGANIC CHEMISTRY; APPARATUS THEREFOR (preparation of carboxylic acid esters by telomerisation C07C67/47; telomerisation C08F)
Introduced: September 1968
Description
Covers general laboratory methods, procedures, and apparatus used across organic chemistry synthesis and analysis that are not specific to individual compound classes or reactions. Includes reaction apparatus, separation techniques, purification methods, protective group strategies, and chemical transformation procedures applicable to diverse organic syntheses. This subclass serves as a catch-all for cross-cutting methodologies and equipment relevant to multiple organic chemistry domains, excluding specialized methods tied to particular functional groups, compound types, or reactions classified elsewhere in C07.

Glossary
Asymmetric synthesis Process that produce optically active compounds from symmetrically constituted molecules by the intermediate use of optically active reagents, but without the use of any of the methods of resolution. Functional group functional groups Group of atoms within a molecule that is responsible for certain properties of the molecule and reactions in which it takes part. Grignard reaction Grignard reactions Addition of organomagnesium compounds (Grignard reagents) to carbonyl groups or other unsaturated groups to give alcohols or ketones. Inversion The spatial rearrangement of atoms or groups of atoms in a dissymmetric molecule, giving rise to a product with a molecular configuration that is a mirror image of that of the original molecule. Racemisation Conversion, by heat or by chemical reaction of an optically active compound into an optically inactive form in which half of the optically active substance becomes its mirror image (enantiomer). This change results in a mixture of equal quantities of dextro- and levorotatory isomers, as result of which the compound does not rotate plane-polarized light to either right or left since the two opposite rotations cancel each other. Separation Means separation only for the purposes of recovering organic compounds
