Cheng, Kai published the artcileSilver-catalyzed decarboxylative acylation of arylglyoxylic acids with arylboronic acids, Quality Control of 197958-29-5, the publication is RSC Advances (2014), 4(89), 48698-48702, database is CAplus.
The silver-catalyzed coupling of arylboronic acids with arylglyoxylic acids was found to be an extremely efficient route for the synthesis of unsym. diaryl ketones. It was conducted on a gram scale under mild and open-flask conditions with good functional group compatibility, avoiding the addition of expensive and/or toxic metals.
