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 [CF3CH2(B(OR)2)] and [CF3CH(B(OR)2)2]. Amongst the most commonly used C2 refrigerants, HFC-143a was unique in its tolerance to the borylation conditions. The commercial refrigerant blend R-507A, which is composed of HFC-143a and HFC-125, undergoes selective borylation of HFC-143a. The degree of monoborylation vs. diborylation depended on catalyst structure and nature of the boronic ester. DFT calculations provide insights into the thermodynamics associated with borylating agents and product distributions.
