abstract = {Colloidal and supported manganese nanoparticles were
synthesized following an organometallic approach and applied
in the catalytic transfer hydrogenation (CTH) of aldehydes
and ketones. Reaction parameters for the preparation of
colloidal nanoparticles (NPs) were optimized to yield small
(2–2.5 nm) and well-dispersed NPs. Manganese NPs were
further immobilized on an imidazolium-based supported ionic
phase (SILP) and characterized to evaluate NP size, metal
loading, and oxidation states. Oxidation of the Mn NPs by
the support was observed resulting in an average formal
oxidation state of +2.5. The MnO$_x$@SILP material showed
promising performance in the CTH of aldehydes and ketones
using 2-propanol as a hydrogen donor, outperforming
previously reported Mn NPs-based CTH catalysts in terms of
metal loading-normalized turnover numbers. Interestingly,
MnO$_x$@SILP were found to lose activity upon air exposure,
which correlates with an additional increase in the average
oxidation state of Mn as revealed by X-ray absorption
spectroscopic studies.},
