<p>We describe a process for the preparation of a ruthenium compound of formula (I): [Ru(dienyl)2], wherein 'dienyl' represents a subsituted pentadienyl or cycloheptadienyl group, which process comprises reacting dichloro(2,7-dimethylocta-2,6-dien-1,8-diyl)-ruthenium with an appropriate diene in the presence of: 1) a primary or secondary alcohol capable of reducing Ru(IV) to Ru(II); and 2) a carbonate of an alkaline metal. The title compounds are useful as precursors of Ru catalysts.</p> |
