- Abstract
We have developed a C−H activation protocol of 2‐arylbenzoxazinones in aqueous medium under open aerial atmosphere at close to room temperature (40 °C) using magnetic Pd‐catalyst. 2‐Arylbenzoxazinones react with phenylglyoxylic acids via decarboxylative C−H acylation followed by cyclization reaction to produce the isoindolinone compounds. The reaction can be arrested at the intermediate step to obtain the ortho‐acylated derivative at a certain lower temperature. The heterogeneous Pd‐catalyst is easy to separate magnetically and shows good recyclability.
