Alexei Eugenivich Chichibabin (Kusemino, nr. Poltava, Russia, 17 March 1871 (O.S.)-Paris, 15 August 1945), assistant in the University of Moscow (1900) and professor (1909) in the Technical High-School there, published much work in organic chemistry, notably on tervalent carbon. The Chichibabin amination reaction (1914) involves the formation of 2-aminopyridine by heating pyridine with sodamide in toluene, and hydrolysis of the product with water. The Chichibabin pyridine synthesis involves the condensation of aldehydes, ketones, etc., with ammonia or amines to form substituted pyridines. ...
