Manganese, the third most abundant transition‐metal element after iron and titanium, has recently been demonstrated to be an effective homogeneous catalyst in numerous reactions. Herein, the preparation of silica‐supported Mn II sites is reported using Surface Organometallic Chemistry (SOMC), combined with tailored thermolytic molecular precursors approach based on Mn 2 [OSi(O t Bu) 3 ] 4 and Mn{N(SiMe 3 ) 2 } 2 ⋅THF. These supported Mn II sites, free of organic ligands, efficiently catalyze numerous reactions: hydroboration and hydrosilylation of ketones and aldehydes as well as the transesterification of industrially relevant substrates.
