  • Patent number: 10017430
    Abstract: Disclosed herein are processes for tandem alkene dehydrogenation/alkene dimerization using an iridium pincer complex catalyst on a support comprising magnesium silicates (e.g., FlorisilĀ®). The reaction process comprises providing an iridium pincer complex bound to a solid support comprising magnesium silicates; providing a gaseous alkane feedstock comprising at least one alkane; and contacting the gaseous alkane feedstock with the iridium pincer complex bound to the solid support in the presence of a hydrogen acceptor to form dimerized alkenes. The processes disclosed herein can accomplish facile, low-temperature tandem transfer dehydrogenation of alkanes and dimerization of alkenes with unprecedented TONs at a reasonable rate of conversion.

  • Publication number: 20180002361
    Abstract: Disclosed herein are processes for dehydrogenation of an alkane to an alkene using an iridium pincer complex. In the dehydrogenation reactions, hydrogen that is co-formed during the process must be removed for the chemical reaction to proceed and to prevent the excess hydrogen from poisoning the catalyst. In one embodiment the process comprises providing an alkane feedstock comprising at least one alkane and contacting the alkane with an iridium pincer complex in the presence of a hydrogen acceptor selected from the group consisting of ethylene, propene, or mixtures to form an alkene product. The processes disclosed herein can accomplish facile, low-temperature transfer dehydrogenation of alkanes with unprecedented selectivities and TONs at a reasonable rate of conversion.

  • Patent number: 7902417
    Abstract: A method of converting at least one first alkane to a mixture of at least one low molecular weight alkane (optionally also including additional lower and/or higher molecular weight alkanes) and at least one high molecular weight alkane, comprising: reacting a first alkane in the presence of dual catalyst system comprising a first catalyst (i.e., a hydrogen transfer catalyst and preferably an iridium pincer complex catalyst) and a second catalyst (i.e., a metathesis catalyst) to produce a mixture of low and high molecular weight alkanes.
