Parnes Zinaida Naumovna (1923–2004)

Doctor of chemical sciences, professor, author of Discovery of USSR «Electrophilic ionic hydrogenation » (1978).

She was an outstanding authority in the area of chemical reactions mechanisms, carbenium ions and hydride mobility of hydrogen atom in organic and organoelement compounds. The substantial result of the investigation was discovering of a new hydrogenation method titled «ionic hydrogenation» (Kursanov-Parnes reaction). This reaction consists in sequential addition of proton (or Lewis acid) and hydride anion to unsaturated bonds. The possibility of hydrogenating pairs variation, the capability of large number of different classes of compounds to this reaction and unique selectivity make ionic hydrogenation a common reaction of organic chemistry.
