CCC-Pincer Ligands for Hydrocarbon FunctionalizationAnthony R. Chianese, Department of Chemistry, Colgate University

Aryl-substituted CCC-pincer ligands were synthesized, and metalation to iridium gives

complexes that catalyze C-H functionalization reactions, including alkane dehydrogenation and

arene borylation.

X-ray structure: Ar = mesityl

These iridium complexes are active catalysts for the borylation of arene C-H bonds:

They are also active catalysts for the acceptorless dehydrogenation of alkanes
