✦ Synopsis

Fourteen ruthenium(II) complexes of the type [RuCl 2 (η 6 -properties are described. The effect of the nature of the benzazole (L) on the catalytic activity of these complexes for arene)L], (arene = 1,4-MeC 6 H 4 Pr i or C 6 Me 6 ; L = benzimidazole derivative in which the NH group is the intramolecular cyclization of (Z)-3-methylpent-2-en-4yn-1-ol into 2,3-dimethylfuran has also been studied; the substituted by N-alkyl or isoelectronic O or S atoms) have been prepared by cleavage of [RuCl 2 (η 6 -arene)] 2 with the N-benzimidazole complexes were found to be the most active. heterocycle L. Their spectroscopic and electrochemical
