2,5-Diazacyclopentadienylidene (2H-imidazolylidene), generated either by photolysis or thermolysis from 2-diazo-2H-imidazole, reacts with benzene derivatives to give mainly a mixture of o-, m-, and p-substituted 2-phenylimidazoles. The carbene shows a strong diradical character, in sharp contrast with the well-known behavior of cyclopentadienylidene.

Abstract The molecular and crystalstructure of 2-(2′-hydroxyphenyl)imidazole (2) and 1-methyl-2-(2′-hydroxyphenyl)imidazole (5) have been determined by X-ray analysis. Compound (2) presents a strong intramolecular hydrogen bond (IMHB) responsible for the planarity of the molecule. In both compounds the molecules form chains through NH…O (compound 2) and OH…N hydrogen bonds (compound 5) but giving
