METHOD OF PRODUCING Α-DIAZOCARBONYL COMPOUNDS IN AQUEOUS MEDIUM Russian patent published in 2019 - IPC C07C245/14 C07C245/18 C07D471/02

Abstract RU 2686489 C1

FIELD: chemistry.

SUBSTANCE: present invention relates to a method of producing aliphatic α-diazocarbonyl compounds of general formula (1) , where R₁₁, R₁₂ have values given in claim 1, by diazo transfer reaction from water-soluble sulphonyl azide (3-carboxyphenylsulphonyl azide) obtained in aqueous solution in situ in form of alkali metal salt from sulphochloride and sodium azide in presence of base.

EFFECT: technical result is universality and simplicity of method, high output of target products and ease of their separation from reaction mixtures, resulting in this method is suitable for industrial use.
