- 摘要:A recyclable fac-tris(heptadecanyl-2-phenylpyridine) iridium [fac-Ir(hdppy)(3)] photocatalyst was synthesized. The hexane-phase-selective solubility of fac-Ir(hdppy)(3) in a thermomorphic multicomponent solvent (TMS) allowed its easy recycling by automatic liquid/liquid separation at room temperature. The excellent catalytic and recoverable activities of fac-Ir(hdppy)(3) were demonstrated via trifuoromethylation and difluoroacetylation reactions of phenyl 3-phenylpropiolate under visible-light irradiation in a TMS system.
