yzed coupling reaction was investigated. Substituted 3-benzylidene-2-arylisoindolin-1-ones were reacted with diphenylphosphineoxide to afford 3-arylidene-2-(2-(diphenylphosphoryl)aryl)isoindolin-1-ones. The reaction proceeded at 25 °C in an air atmosphere in the absence of base and ligands. Our results indicate that the diphenylphosphineoxide free radical tends to attack the aryl rather than the
研究了一种新型的Pd(OAc)2 / Ag 2 CO 3催化的偶联反应。使取代的3-亚苄基-2-芳基异吲哚啉-1-酮与二苯基膦氧化物反应,得到3-亚芳基-2-(2-(2-(二苯基磷酰基)芳基)异吲哚啉-1-酮。该反应在空气气氛中于25℃在没有碱和配体的情况下进行。我们的结果表明,在该反应中,二苯基氧化膦自由基倾向于攻击芳基而不是双键。

substituted-3-hydroxy-2-aryl-3-(2,2,2-trifluoro-1-arylethyl)isoindolin-1-one. The reaction proceeded at 25 °C in air atmosphere in the absence of base and ligands. Our results indicate that trifluoromethyl free radical tends to attack a double bond rather than aryl in this reaction.
