摘要:
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-13{F-19} NMR spectroscopies. Removal of the HF solvent in vacuo yielded the tetrameric [{Os(CO)3F2}4].
