    摘要: A series of new bis(imino)pyridine vanadium(III) complexes was synthesized according to formula: They were tested for the homogeneous catalytic dimerization of propylene after activation with MAO and showed excellent selectivity for dimerization. The catalysts can be used with or without PPh3 as an additive to produce ≧80% dimerized alkenes.

    摘要: A catalyst comprising a 1) complex comprising: a) at least one metal selected from the group consisting of Group 8 metals, Group 9 metals, Group 10 metals, and combinations thereof; b) a compound having the formula R3X wherein R is selected from the group consisting of hydrogen, an alkyl, an alkenyl, an alkynyl, cycloalkyls, cycloalkenyls, cycloalkynyls, aryls, substituted aryls, and substituted organic compounds and wherein X is a Group 15 element selected from the group consisting of nitrogen, phosphorus, arsenic, antimony and bismuth; and 2) support component comprising a silicon-containing compound and a method of making said catalyst, is disclosed. The catalyst is then used to dehydrogenate hydrocarbons in a dehydrogenation reaction zone under dehydrogenation reaction conditions.
