The invention concerns an alkane metathesis catalyst, its production and use. The catalyst comprises a Group V, VI or VII metal alkyl with the metal in its highest oxidation state, preferably Ta or W, and the alkyl of C1-C4, preferably together with alkylidene and/or alkylidyne ligands, in particular -Me, ═CH2 and ≡CH, on a metal oxide support, preferably silica partially dehydroxylated at 200 or 700° C. Substrates include cycloalkanes, preferably cyclooctane.
这项发明涉及烷基置换催化剂及其制备和使用。该催化剂包括一种V、VI或VII族金属烷基,其中金属处于其最高氧化态,优选为Ta或W,以及C1-C4烷基,优选与烷基亚甲基和/或烷基炔基配体一起使用,特别是-Me,═CH2和≡CH,在金属氧化物支撑物上,优选为在200或700°C部分脱氢的二氧化硅。底物包括环烷烃,优选为环辛烷。
