  摘要：

  Bromotricarbonylrhenium(I) complexes [ReBr(CO)(3)L] [L = Ph2PO(CH)(3)OPPh2 (L), (Pr2PO)-Pr-i(CH2)(2)(OPPr2)-Pr-i (L-2), Cy2PO-(CH2)(2)OPCy2 (L)] were prepared by reaction of [ReBr(CO)51 with L. X-ray crystallography showed them all to be mononuclear, with the CO ligands fac. Subsequent reaction with AgOTf gave fac-[Re(OTf(CO)(3)L], as shown by IR and NMR spectra. By contrast, reaction of [ReH(CO)(5)] with L1-3 gave hydrido complexes, the nuclearity and stereochemistry of which depended on the identity of L, as was confirmed by X-ray crystallography of mer-[ReH(CO)(3)L-1], fac-[ReH(CO)(3)L-2] and [(ReH(CO)4}2(p-L 3)]. Protonation of the hydrido compounds at 183 K with HBF4 center dot OMe2 gave the corresponding non-classical cationic dihydrogen complexes (T-1(min) similar to 15 ms at 400 MHz), which released H-2 at temperatures above critical temperatures (243-263 K) that depended oil the co-ligands.
