• performances than copper salts, even with lower catalyst loading and under milder conditions [49][50][51]. Based on this background, the first potential formic acid dehydrogenation catalyzed by NHC–Cu complexes (Figure 1) was investigated. Results and Discussion We have shown that the reaction of [Cu(OH)(IPr
