Reference of 131274-22-1, An article , which mentions 131274-22-1, molecular formula is C12H28BF4P. The compound – Tri-tert-butylphosphonium tetrafluoroborate played an important role in people’s production and life.
An efficient Pd-catalyzed carbonylative alpha-arylation of 2-oxindoles with aryl and heteroaryl bromides for the one-step synthesis of 3-acyl-2-oxindoles has been developed. This reaction proceeds efficiently under mild conditions and is complementary to the more common oxindole forming reactions. The transformation only requires a mild base and provides good to excellent yields even with heteroaromatic substrates. Employing a near stoichiometric amount of 13COgen, the methodology was easily extended to [13C] acyl labeling. The general applicability of the reaction conditions was demonstrated in the synthesis of a structure related to the pharmaceutically active 3-acyl-2-oxindoles, tenidap. Carbonylate it. 3-Acyl-2-oxindoles are directly obtained through an efficient Pd-catalyzed carbonylative alpha-arylation of 2-oxindoles with aryl and heteroaryl bromides. Only a mild base is required for the deprotonation and good to excellent yields are obtained even with heteroaromatic substrates.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 131274-22-1, help many people in the next few years., Reference of 131274-22-1
