• fluorinated materials are non-flammable and have low toxicity, CFCs were found to be destructive to the ozone layer of the stratosphere [1][2] due to high ozone-depleting potential (ODP). This has led to the phasing out of CFCs and the replacement with hydrofluorocarbons (HFCs), which show no significant

• source [50]. In the presence of silane and ACF, HFO-1233xf was further activated via allylic hydrodefluorination. In this paper, we report on the reactivity of ACF towards hydrofluorocarbons, and in particular, the pentafluoropropane isomers (HFC-245). Effective hydrodefluorination and
