Abstract
Novel group 6 organometallic compounds, supported on anions by means of at least one covalent metal-oxygen bond, are obtained by reaction of at least one borate or aluminate comprising at least one hydroxy group with at least one compound of a group 6 transition metal. These compounds are used in a catalytic composition utilized in an olefin metathesis method.
