Novel metal complexes, particularly chromium complexes, which contain at least one tridentate ligand are disclosed and prepared. Olefins, particularly ethylene, can be reacted to form butene and/or other homo- or co-oligomers and/or polymers with high .alpha.-olefin concentrations by contacting a metal catalyst which contains a transition metal, particularly chromium, complexes having per metal atom at least one tridentate ligand with N, O, or N and O coordinating sites.
L'invention a trait à de nouveaux complexes métalliques, en particulier des complexes de chrome, contenant au moins un ligand tridenté, ainsi qu'à leur préparation. Des oléfines, notamment l'éthylène, peuvent être mises en réaction en vue de former du butène et/ou d'autres homo-oligomères ou co-oligomères et/ou polymères avec des concentrations d'alpha-oléfine élevées par contact présentant un catalyseur métallique comprenant un métal de transition, en particulier du chrome, des complexes comportant par atome métallique au moins un ligand tridenté avec N, O, ou des sites coordonnant N et O.
