A facile synthesis of aryl esters is developed by coupling aryl carboxylicacids and aryl boronicacids in the presence of PhI(OAc)2 and carbonyl diimidazole. A wide range of functional groups were tolerant to the metal-free reaction condition that led to the desired products in good yields.
transfer reaction of aromatic esters with aryl halides/arenols was developed. The present reaction can transfer an ester functional group from certain aromatic esters to haloarenes. This ester transfer reaction involves two oxidative additions—one from the C–C bond of the aromatic ester and one from the C–halogen bond of haloarenes—onto a nickel catalyst. The utilization of a Ni/dcypt catalyst capable
A process for producing an aromatic carbonate which comprises: reacting a dialkyl carbonate represented by general formula (1) with an aromatic carboxylic acid aryl ester represented by general formula (2) in the presence of a catalyst to produce an aromatic carbonate represented by one or both of general formulae (3) and (4):
R-OCOO-R (1)
Ar'-COO-Ar (2)
Ar-OCOO-R (3)
Ar-OCOO-Ar (4)
wherein R represents an alkyl group having from 1 to 4 carbon atoms, and Ar and Ar' each represents an unsubstituted phenyl group or a phenyl group substituted by a substituent selected from the group consisting of alkyl, alkoxy, aryl, aryloxy and a halogen atom.
