Publisher Summary This chapter seeks to cover all known 2H-imidazoles. The most important synthetic routes for the synthesis of 2H-imidazoles have been from ketones by cyclization, by the transformation of imidazolone derivatives, and by the reaction between 1H-imidazoles and electrophiles.

A Pd(OAc)2-catalyzed divergent synthesis of multisubstituted imidazoles and quinazolines from N-allylamidines has been developed. In the presence of oxidant O2 from air and/or a ligand and Pd(OAc)2, imidazoles were obtained. Nonetheless, under microwave (

N-(Chlorosulfinyl)-imidazole as a New Imidazole Transfer Reagent
HETEROCYCLES, 1980Abstract The usefulness of diimidazoles2 such as N, N′-carbonyldi-imidazole (1), and N, N′-thionyldiimidazole (2) in organic synthesis has been accumulated recently. In connection with the continuing our studies on the reaction using 1 or 2 3 (carbonyl, thionyl, and imidazole transfer reactions), our particular interest was focused on the synthesis of ...

On the photochemical phosphorylation of imidazole
Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1972Abstract It has not proved possible to repeat the reported anaerobic photophosphorylation of imidazole to produce imidazole 1-phosphate. The involvement of an analogous reaction in mitochondrial oxidative phosphorylation is therefore further in doubt.

The Journal of Physical Chemistry A, 2012
The respective structures and stabilities of imidazole-imidazole, benzene-imidazole, and benzene-indole dimers have been investigated using different DFT-D functional, MP2, CCSD(T), and SAPT levels of theory with a medium basis set. Comparative analysis of binding energies and structural parameters of the dimers points to a preference for stacking ...
