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
