The silver-catalyzed coupling of arylboronic acids with arylglyoxylic acids was found to be an extremely efficient route for the synthesis of unsymmetrical diaryl ketones. It can be 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.

measurements. The results indicated the inhibition performance followed the order of η(AA) > η(MA) > η(CA), and these acridines acted as mixed type inhibitors with a predominant restrained cathode process. The adsorption of the three acridines on a mild steel surface obeyed the Langmuir adsorption isotherm and involved both physisorption and chemisorption modes. Surface analysis and characterization confirmed
