  abstract     = {{<p>Acceptorless alcohol dehydrogenation (AAD) converts alcohols to carbonyl compounds with concurrent hydrogen evolution, providing a sustainable and atom-efficient oxidation pathway. Here, we examine how electronic modifications of POCOP-type iridium pincer catalysts influence this transformation. A CF<sub>3</sub>-substituted complex exhibits a 3–7 times higher initial turnover frequency relative to the parent system in the dehydrogenation of 1-phenylethanol. Kinetic analysis shows that this enhancement reflects a lower intrinsic β-hydride elimination barrier, although slow hydrogen mass transfer partially masks the full activity advantage at elevated temperatures. These results establish ligand electronic manipulation as a direct method for accelerating AAD catalysis rather than merely improving stability.</p>}},
