Patent

CA 2470885

The invention provides a mixed heteroatomic ligand for an oligomerisation of olefins catalyst, which ligand includes at least three heteroatoms, of which at least one heteroatom is sulfur and at least 2 heteroatoms are not the same.The invention also provides a multidentate mixed heteroatomic ligand for an oligomerisation of olefins catalyst, which ligand includes at least three heteroatoms of which at least one is a sulfur atom. The ligand may also contain, in addition to sulfur, at least one nitrogen or phosphorous heteroatom.

La présente invention concerne un ligand hétéroatomique mixte qui est destiné à une oligomérisation d'un catalyseur d'oléfines et qui comprend au moins trois hétéroatomes, dont au moins un est du soufre, au moins deux hétéroatomes étant différents. La présente invention concerne également un ligand hétéroatomique mixte multicoordinant qui est destiné à une oligomérisation d'un catalyseur d'oléfines et qui comprend au moins trois hétéroatomes, dont au moins un est un atome de soufre. Le ligand peut également contenir, outre le soufre, au moins un hétéroatome d'azote ou de phosphore.
