Abstract
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(PPh3)], cis-[Os(OTeF5)(CO)4Me] and cis-[Re(OTeF5)(CO)4(PPh3)], 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 –).Keywords
