A series of rate studies were conducted to evaluate the steric and electronic properties that govern the reactivity of iodoarene amide catalysts in the α-oxytosylation of propiophenone. A meta-substituted benzamide catalyst emerged as the most reactive. This catalyst was employed in the α-oxytosylation of a series of substituted propiophenones, returning the α-tosyloxy ketone products in excellent

environmental-benign compound prepared from CO2, shows diverse reactivity. In this communication, a palladium-catalyzed Intramolecular carbopalladation and Carbonylation has been explored for the synthesis of functionalized isoquinoline-1,3-diones and oxindoles by using DMC as both green solvent and reactant. Moreover, formic acid is employed as the CO source in this reaction.
碳酸二甲酯 (DMC) 是一种由 CO 2制备的对环境无害的化合物,具有多种反应性。在本次交流中,已经探索了钯催化的分子内碳钯化和羰基化,以使用 DMC 作为绿色溶剂和反应物来合成功能化的异喹啉-1,3-二酮和羟吲哚。此外,甲酸用作该反应中的CO源。
