Cläre Hunsdiecker
Cläre () Hunsdiecker (1903-1995) was a German Chemist who worked with her husband Heinz Hunsdiecker to improve a reaction of Alexander Borodin now known as the Hunsdiecker reaction The Hunsdiecker reaction (also called the Borodin reaction or the Hunsdiecker–Borodin reaction) is a name reaction in organic chemistry whereby silver salts of carboxylic acids react with a halogen to produce an organic halide. It is an exam .... They received both US and German patents for the work. Education Hunsdiecker earned her Ph.D. from the University of Cologne. For many years it was not believed that a photographic image of Hunsdiecker was in existence. In 2020 an image was located by an undergraduate student at the University of Melbourne.

Hunsdiecker Reaction
The Hunsdiecker reaction (also called the Borodin reaction or the Hunsdiecker–Borodin reaction) is a name reaction in organic chemistry whereby silver salts of carboxylic acids react with a halogen to produce an organic halide. It is an example of both a decarboxylation and a halogenation reaction as the product has one fewer carbon atoms than the starting material (lost as carbon dioxide) and a halogen atom is introduced its place. The reaction was first demonstrated by Alexander Borodin in his 1861 reports of the preparation of methyl bromide () from silver acetate (). Shortly after, the approach was applied to the degradation of fatty acids in the laboratory of Adolf Lieben. However, it is named for Cläre Hunsdiecker and her husband Heinz Hunsdiecker, whose work in the 1930s developed it into a general method. Several reviews have been published, and a catalytic approach has been developed. : History Alexander Borodin first observed the reaction in 1861 when he prep ...
