  Reactions of cis-[Os(CO)4Me2] and cis-[Re(CO)4(PPh3)Me] with anhydrous HF and HOTeF5; compatibiltiy of phosphine, alkyl and OTeF5 ? ligands in low-valent transition-metal complexes

  摘要：

  In the reactions of transition metal carbonyl methyls with HF or HOTeF5 the elimination of methane has been shown to be a strong driving force in the formation of, for example, cis-[OsF2(CO)(4)], cis-[ReF(CO)(4)(PPh(3))], cis-[Os(OTeF5)(CO)(4)Me] and cis-[Re(OTeF5)(CO)(4)(PPh(3))], which have been characterised by a combination of multinuclear NMR spectroscopic studies. These results also indicate that, with a suitable choice of metals and co-ligands. transition-metal teflate-phosphine and teflate-alkyl complexes can be prepared (teflate = OTeF5-).

  The oxidative fluorination of [Os3(CO)12] with XeF2 in anhydrous HF afforded, in solution, cis-[Os(CO)4F2] as the major product with [Os(CO)5F]+, [Os2(CO)7F4] and [Os2(CO)8F3]+ as minor products, all of which have been characterised by C-13, F-19 and C-13F-19} NMR spectroscopies. Removal of the HF solvent in vacuo yielded the tetrameric [Os(CO)3F2}4].
