Chemistry of Heterocyclic Compounds Aims and scope

Abstract

The basicities of 3-methyl-4-R-furazans (R = H, CH3, C2H5, n-C3H7, NH2 NHAcOCH3, I, COOH, and NO2) were investigated by PMR spectroscopy. It is shown that they are weak bases, the protonation of which is described by the HA acidity function. Relationships between the chemical shifts of the protons of the methyl group and the σR ° constants and the p KaBH + and the σM ° constants of the substituents were found.
