TBuOK facilitated addition of diarylmethanes to styrenes through a radical reaction mechanism

Abstract

Herein, we described the alkali-facilitated bonding of diarylmethanes to alkenes through a radical pathway. Diaryl compound products can be obtained under mild conditions with good yields. The reaction employed a practical approach by utilizing only 10% potassium tert-butoxide to synthesize diaryl compounds through a radical mechanism. The radical nature of this reaction was confirmed through radical capture experiments and EPR. Furthermore, we substantiated this characteristic with experimental evidence such as kinetic study and isotope labeling experiments.
