In the wake of a great master: Guido Pellizzari (1858-1938)
Guido Pellizzari (1858-1938) was the first of Hugo Schiff’s (1834-1915) students to become university professors. Guido Pellizzari specialized in organic chemistry. The preparation of 1,2,4-triazole derivatives by baking a mixture of an amide and an acyl hydrazide is also referred to as the Pellizzari reaction. This reaction has been applied for the preparation of mono-substituted-, bi-substituted-, and tri-substituted 1,2,4-1H-triazoles.
Professor at the University of Catania and Cagliari, in 1891 Pellizzari occupied the chair of chemistry at the University of Genoa and in 1916 he moved to the “Istituto di Studi Superori Pratici e di Perfezionamento” (later University of Florence) in Florence. Guido Pellizzari performed various researches in the field of organic chemistry. The preparation of 1,2,4-triazoles for dry heating of mixtures of aliphatic amides and hydrazides was named after him. It has been reported that co-heating a mixture of formamide and hydrazine hydrochloride with pulverized KOH can improve the yield of 1,2,4-triazole. This reaction has been applied for the preparation of mono-substituted-, bi-substituted-, and tri-substituted 1,2,4-1H-triazoles.
