Process for the preparation of ruthenium compounds

   
   

A process for the preparation of ruthenium compounds of the formula {Ru(dienyl).sub.2 } wherein "dienyl" represents a substituted pentadienyl or cycloheptadienyl group by reacting dichloro(2,7-dimethylocta-2,6-dien-1,8-diyl)-ruthenium with an appropriate diene in the presence of a primary or secondary alcohol capable of reducing Ru(IV) to Ru(II); and a carbonate of an alkaline material. These ruthenium compounds are useful as precursors of Ru catalysts.

Un proceso para la preparación de los compuestos del rutenio del fórmula {Ru(dienyl).sub.2} en donde el "dienyl" representa a grupo substituido del pentadienyl o del cycloheptadienyl reaccionando dichloro(2,7-dimethylocta-2,6-dien-1,8-diyl)-ruthenium con un diene apropiado en la presencia de un alcohol primario o secundario capaz de reducir Ru(IV) a Ru(II); y un carbonato de un material alcalino. Estos compuestos del rutenio son útiles como precursores de los catalizadores del Ru.
