Synthesis and characterisation of osmium carbonyl fluorides
Abstract
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 13C, 19F and 13C-{19F} NMR spectroscopies. Removal of the HF solvent in vacuoyielded the tetrameric [{Os(CO)3F2}4].
