Carbon Double Bond

A variety of α,β-unsaturated esters and cyclic ketones underwent smooth reduction of the carbon–carbon double bond with a combination of inexpensive and readily available trichlorosilane and CoCl2. The reactions are performed under very mild conditions and products are obtained in high yields.Key words: reduction, carbonyl compounds, trichlorosilane, ketones, chemoselectivity.

Work Up

Olefins, dienes, and trienes can be hydrogenated in an aqueous–organic two-phase medium using the dimer of chloro(1,5-hexadiene)rhodium as the catalyst. Selective reduction of the double bond of α,β-unsaturated carbonyls occurs in high yields. These reactions occur at room temperatures and atmospheric pressure, and are simple to work-up.
