N1,N2-Bis(2,6-dimethylphenyl)-N1-hydroxyformamidine N,N′-bis(2,6-dimethylphenyl)-N-oxidoformamidinium dichloromethane solvate

Abstract

The title compound, 2C17H20N2O·CH2Cl2, was obtained by N-oxidation of the parent formamidine with m-chloro-peroxybenzoic acid (m-CPBA). This is the first use of the above-mentioned synthetic route for the preparation of hydroxyamidines. The title compound crystallizes as a cyclic dimer resulting from the presence of O—H...O and N—H...N hydrogen bonds.
