Rizwan, Komal published the artcilePalladium catalyzed cross-coupling of 3-methylthiophene-2-carbonyl chloride with aryl/het-aryl boronic acids: a convenient method for synthesis of thienyl ketones, Synthetic Route of 724710-02-5, the publication is Journal of Sulfur Chemistry (2022), 43(5), 494-506, database is CAplus.
A protocol for the synthesis of thienyl ketones was developed via Pd(0) catalyzed cross-coupling reaction. The desired thienyl ketones were synthesized by cross coupling of 3-methylthiophene-2-carbonyl chloride with variety of aryl/heteroarylboronic acids in good to excellent yields (46-91%) under mild conditions (1.5 equiv Cs2CO3 at 50°C). Different functional groups were well tolerated under the developed reaction conditions.
