It is employed as a reactant involved in 1,4-conjugate addition reactions with ethenesulfonamides to form arylethanesulfonamides, Suzuki-Miyaura reactions with dibromotrifluoromethylbenzene, cross-coupling reactions with diazoesters3 or potassium cyanate. It is involved in the synthesis of biarylketones and phthalides and synthesis of inhibitors including PDE4 inhibitors6 among others.
