Purification Methods

It is recrystallised repeatedly from de-aerated cyclohexane in the dark or from pet ether/*C6H6 and forms yellow needles. It is soluble in H2O, EtOH and *C6H6, and forms a monohydrate which loses H2O at 60o. The picrate has m 207o(dec). [Nozoe et al. J Am Chem Soc 76 3352 1954, Nukai et al.

A tropylium annulated N-heterocyclic carbene

Derivatives of the cationic tropylium annulated imidazolylidene ITrop+ are obtained by hydride abstraction from related cycloheptatriene compounds. Spectroscopic, structural and theoretical data indicate that, as a cationic relative of benzimidazolylidenes, ITrop+ has highly reduced σ-donor and strong π-acceptor character.

Methine dyes

Methine dye which contains a cycloheptimidazole nucleus having a substituent at its 1-position thereof and in which the 7-membered ring moiety is substituted by a methine bond having an auxochrome, at the terminal thereof, for forming a conjugated resonan
