英文摘要While numerous single atoms stabilized by support surfaces have been reported, the synthesis of in-situ reduced discrete metal atoms weakly coordinated and stabilized in liquid media is a more challenging goal. We report the genesis of mononuclear electron deficient Pt-1(0) by reducing H2PtCl6 in liquid polydimethylsiloxane-polyethylene glycol (PDMS-PEG) (Pt-1@PDMS-PEG). UV-Vis, far-IR, and X-ray photoelectron spectroscopies evidence the reduction of H2PtCl6. CO infrared, and Pt-195 and C-13 NMR spectroscopies provide strong evidence of Pt-1(0), existing as a pseudo-octahedral structure of ((ROR2)-O-1)(2)Pt(0)Cl2H2 (R-1 and R-2 are H, C, or Si groups accordingly). The weakly coordinated ((ROR2)-O-1)(2)Pt(0)Cl2H2 structure and electron deficient Pt-1(0) have been validated by comparing experimental and DFT calculated Pt-195 NMR spectra. The H+ in protic state and the Cl- together resemble HCl as the weak coordination. Neutralization by a base causes the formation of Pt nanoparticles. The Pt-1@PDMS-PEG shows ultrahigh activity in olefin hydrosilylation with excellent terminal adducts selectivity.
