Costin Nenițescu

Costin D. Neniţescu (in some plaCES Nenitzescu (Romanian pronunciation: [kosˈtin neniˈt͡sesku]; 15 July 1902 – 28 July 1970)) was a prominent Romanian chemist, and a professor at the Polytechnic University of Bucharest. He was a member of the Romanian Academy, a corresponding member of the German Academy of Sciences in Berlin, and a member of the Leopoldina Academy of Natural Scientists in Halle-Saale.

Early life

After completing in 1920 his secondary studies at Gheorghe Lazăr High School, Neniţescu continued his studies at the Polytechnic Institute in Zürich and Ludwig Maximilian University in Munich, where he was one of the favorite students of Hans Fischer.[1]

Career

He studied Friedel–Crafts-like reactions in the series of aliphatic hydrocarbons, the mechanism of the isomerization of cyclobasics, the halogen migration in cycles and chains, reactions induced by carbonium ions, and others. He identified a group of naphthenic acids in Romanian oil. He searched for ways of obtaining cyclobutadiene, while explaining the chemistry of this unstable substance and isolating its dimers.

His research interests included the oxidation of open-chain and aromatic hydrocarbons with chromic acid and chromic oxychloride. He found new methods for the synthesis of pyrylium salts (Balaban–Nenitzescu–Praill synthesis), of carbenes, tryptamine, serotonin, two new syntheses for the indole nucleus, and a new method of polymerisation of ethylene.[2]

His research was substantiated in more than 200 papers. His remarkable technical and scientific activity helped develop the chemical industry in Romania.[3]

A preferred quote is:

"To be able to convey science you have to be yourself a creative scientist, or at least you should strive to be".

In his honor, the chemistry contest "C.D. Neniţescu" is organized yearly at the Polytechnic University of Bucharest.
