Résumé
The transfer hydrogenation of carbonyl compounds into alcohols with isopropanol has emerged as agreen alternative to the use of hazardous reducing agents. Ni(0) nanoparticles have been described asan efficient catalyst for this reaction, while their classical preparation is still associated with a numberof safety and environmental concerns. Here, we report a sustainable, ecological and straightforwardpreparation of a biosourced Ni(0) based material, by thermal decomposition of Ni(II) formate made from aNi hyperaccumulating plant. The resulting catalyst, EcoNi(0), shows high catalytic activity and selectivityfor the transfer hydrogenation of carbonyl compounds, including challenging aldehydes. The processseeks to be an incentive for the economic development of phytoextraction.
