Abstract

Stoichiometric alkane dehydrogenation utilizing an Ir^III pincer complex, (^dmPhebox)Ir(OAc)₂(OH₂) (1a), has been described. The reaction between 1a and octane resulted in quantitative formation of (^dmPhebox)Ir(OAc)(H) (3a) and octene. At early reaction times 1-octene is the major product, indicative of terminal C-H activation by 1a. In contrast to prior reports of alkane dehydrogenation with Ir, C-H bond activation occurs at Ir^III and the dehydrogenation is not inhibited by nitrogen, olefin, or water.
