The simultaneous immobilization of a Rhcomplex and a tertiary amine on a SiO2 surface afforded a highly active supported catalyst for the hydrosilylation of terminalolefins. The turnover number in the reaction using 0.00005 mol % of the Rh catalyst approached 1 900 000 over 24 h. A broad range of terminalolefins and hydrosilanes acted as good substrates, giving their corresponding hydrosilylation

Pt(II)−NHC complexes are used in alkene hydrosilylation reactions. Some of the examined compounds display excellent catalytic activity, outperforming Pt(0)−NHC pre-catalysts. Our study explores the catalyst structure-activity relationship and provides new mechanistic insights into this industrially important transformation. A sustainable protocol, featuring efficient platinum removal, allows us to
