Abstract: The present disclosure provides a method for the oxidative dehydrogenation of an alkane, e.g., ethane, propane, etc. In embodiments, a method for oxidative dehydrogenation of an alkane comprises exposing a gas comprising an alkane having 2 or more carbons to elemental sulfur vapor at an elevated reaction temperature and for a period of time to convert the alkane to one or more products via oxidative dehydrogenation, the one or more products comprising a primary alkene.

Abstract: Low molecular weight, highly branched polyolefins are provided. Also provided are catalyst-mediated methods of making the low molecular weight, highly branched polyolefins and a catalyst system for carrying out the methods. The catalyst system is a homogeneous catalytic system that includes a single-site organozirconium complex and hydrocarbon-soluble perfluoroarylborate co-catalyst that is highly active for the oligomerization of olefin monomers in non-polar media.
