Formula: C8H8O2. In 2019.0 J ORG CHEM published article about C-C; ARYLATION; COPPER; HYDRAZONES; MILD in [Onodera, Shunsuke; Kochi, Takuya; Kakiuchi, Fumitoshi] Keio Univ, Fac Sci & Technol, Dept Chem, Kohoku Ku, 3-14-1 Hiyoshi, Yokohama, Kanagawa 2238522, Japan in 2019.0, Cited 40.0. The Name is 4′-Hydroxyacetophenone. Through research, I have a further understanding and discovery of 99-93-4.
A method for the synthesis of N-arylpyrazoles by palladium-catalyzed coupling of aryl triflates with pyrazole derivatives is described. Using tBuBrettPhos as a ligand, the palladium-catalyzed C-N coupling of a variety of aryl triflates including ortho-substituted ones with pyrazole derivatives proceeded efficiently to give N-arylpyrazole products in high yields. 3-Trimethylsilylpyrazole was found to be an excellent pyrazole substrate for the coupling, and the corresponding product, 1-aryl-3-trimethylsilylpyrazole, also served as a great template for the syntheses of N-arylpyrazole derivatives, as demonstrated by regioselective halogenation at the 3-, 4-, and 5- positions of the pyrazole ring.
