Abstract
The reaction of N,N-bis(2-(diisopropylphosphaneyl)ethyl)prop-2-yn-1-amine 1 with [Ru(CO)ClH(PPh3)3] leads to the formation of a new class of cyclometallated PNPC pincer complexes. Several examples of this class of compounds are synthesized and characterized. They, specifically complexes 2 and 3, show good to excellent activity and selectivity in additive-free formic acid dehydrogenation, and transfer (de)hydrogenation reactions of different functional groups (ketone, alkyne, and alcohol). Theoretical and experimental studies reveal two competing pathways for the dehydrogenation of formic acid. The Ru-H pathway proceeds via the coordination site trans to the propylene arm of the ligand, whereas in the Ru-C pathway, a de-coordination of the propylene arm is observed.
期刊介绍：
With an impact factor of 4.495 (2018), ChemCatChem is one of the premier journals in the field of catalysis. The journal provides primary research papers and critical secondary information on heterogeneous, homogeneous and bio- and nanocatalysis. The journal is well placed to strengthen cross-communication within between these communities. Its authors and readers come from academia, the chemical industry, and government laboratories across the world. It is published on behalf of Chemistry Europe, an association of 16 European chemical societies, and is supported by the German Catalysis Society.
