摘要
PURPOSE: A method for preparing 2-aryl allenoate derivatives is provided to obtain 2-aryl allenoate derivatives with high yield through a cross coupling reaction of an organic indium reagent in the presence of an arene derivative and palladium catalyst, wherein the organic indium reagent is obtained in in-situ from the reaction of indium with 4-bromo-2-butenoate. ;CONSTITUTION: A method for preparing 2-aryl allenoate derivatives is represented by chemical formula 1. In chemical formula 1, R^1 and R^5 are hydrogen, (C1~C7) alkyl, halogen, (C6~C20) aryl or (C1~C7) alkoxycarbonyl; R^2 and R^4 are hydrogen, (C1~C7) alkoxy or nitro; R^3 is hydrogen, (C1~C7) alkyl, (C6~C20) aryl, halogen, formyl, acetyl, alkoxycarbonyl or (C6~C20) aryl (C1~C7) alkylcarbamoyl aryl; R^6 is hydrogen or (C1~C7) alkyl; and R^7 is (C1~C7) alkyl or (C6~C20) aryl.;COPYRIGHT KIPO 2011
