N 1N 2-Bis­(26-di­methyl­phen­yl)-N 1-hydroxyformamidine NN′-bis­(26-dimethyl­phen­yl)-N-oxidoformamidinium dichloro­methane solvate

摘要

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.
