Genesis of electron deficient Pt1(0) in PDMS-PEG aggregates

Synthesis of discrete reduced metal atoms weakly coordinated and stabilized in liquid media remains challenging. Here, the authors report the genesis of mononuclear electron deficient Pt1(0) in polydimethylsiloxane-polyethylene glycol aggregates, and its ultrahigh activity in olefin hydrosilylation with excellent terminal adducts selectivity.
