The triphenylphosphine-cyclopalladated ferrocenylimine (Cat. 2) exhibited highly catalytic activity for the both of arylboronic acids with carboxylic anhydrides and acyl chlorides with low catalyst loading (0.5 mol %). The reactions were unaffected by the presence of electron-releasing and electron-withdrawing substituents in both the arylboronic acids and carboxylic derivatives. Up to 98% yield was obtained for 32 examples. However, they were limited for arylboronic acid with strong electron-withdrawing groups. It is noting that catalyst 2 can be reused for eight times without losing its catalytic activity. (C) 2012 Elsevier Ltd. All rights reserved.
