Abstract

Silica-bound cis-dicarbonyl-μ-chloro [μ-[2-(trioxysilyl)ethanethiolato-S:S]bis[tris(1,1-dimethylethyl)phosphine]dirhodium (1) was shown to catalyze the disproportionation of 1,3-cyclohexadiene and of 1,2-dihydro-naphthalenes, accompanied by ≤10% dehydrogenation. The formation of tetralins and naphthalenes was found to be strongly affected by the electronic nature of the starting 1,2-dihydronaphthalene derivatives. The effect of hydroxylic solvents on the disproportionation reaction was demonstrated by application of CD3OD. A mechanism which involves both metallic centers of the dinuclear complex is proposed.
