Abstract

The alkylation of 5,5′-diaryl-2,2′-biimidazole-1,1′-diols with an equimolar amount of methyl iodide gave the corresponding N-methyl derivatives, and the reaction with 3 equiv of methyl iodide afforded alkylation products at the nitrogen atom and both hydroxy groups. 5,5′-Diaryl-1H,1′H-2,2′-biimidazoles were obtained by treatment of the title compounds with triphenylphosphine.
