Abstract

Tandem catalyst systems, comprising pincer-ligated iridium-based catalysts for alkane dehydrogenation and catalysts for olefin metathesis, have been found to effect the overall catalytic disproportionation/metathesis of n-alkanes to give exclusively n-alkane products. Under some conditions (but not generally) selectivity is obtained for C(2n-2) alkane plus ethane from 2 mol C(n) alkane. Mechanistic and computational investigations have addressed issues of rates and selectivity. Systems comprising soluble and heterogeneous catalysts will be discussed. Significant progress has been made toward the development of systems with supported pincer complexes; in some cases the supported systems afford longer lifetimes and rates comparable to or even greater than their solution phase analogues.
