This invention provides metal complexes being useful as catalyst components in metathesis reactions and in reactions involving the transfer of an atom or group to an ethylenically or acetylenically unsaturated compound or another reactive substrate and, with respect to a sub-class thereof, for the polymerisation of α-olefins and optionally conjugated dienes, with high activity at moderate tempera-tures. It also provides methods for obtaining polymers with very narrow molecular weight distribution by means of a living reaction. It also provides methods for making said metal complexes and novel intermediates involved in such methods. It further provides derivatives of said metal complexes which are suitable for covalent bonding to a carrier, the product of such covalent bonding being useful as a supported catalyst for heterogeneous catalytic reactions. It also provides a direct one-step synthesis of pyrrole, furan and thiophene compounds from diallyl compounds.
本发明提供了金属配合物,可用作交换反应中的催化剂组分,以及涉及将原子或基团转移至乙烯基或乙炔基不饱和化合物或其他反应底物的反应中,并且针对其亚类别,用于α-烯烃和可选的共轭二烯的聚合,具有在中等温度下高活性。它还提供了通过活性反应获得非常窄的分子量分布的聚合物的方法。它还提供了制备该金属配合物和涉及这种方法的新型中间体的方法。它还提供了该金属配合物的衍生物,适用于与载体进行共价键合,该共价键合的产物可用作异相催化反应的支持催化剂。它还提供了从双烯基化合物直接合成吡咯、呋喃和噻吩化合物的一步法。
