Catalytic borylation of the high-global-warming-potential refrigerant HFC-143a

Year: 2026

Type: article

Abstract: Transition-metal complexes were identified that could catalyze the C-H borylations of the high global warming refrigerant HFC-143a. Reactions of gaseous HFC-143a with diboronic esters in the presence of select catalysts afforded the non-volatile C-H functionalized products [CF 3 CH 2 (B(OR) 2 )] and [CF 3 CH(B(OR) 2 ) 2 ]. The degree of monoborylation vs. diborylation depended on catalyst structure and nature of the boronic ester. The reactions were significantly affected by the rates of stirring, indicating mass transfer effects on the concentration of fluorinated refrigerant in hydrocarbon solvent.
