| 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. |
