Microwave-assisted Cu-catalyzed protodecarboxylation of aromatic carboxylic acids.
An effective protocol has been developed that allows the smooth protodecarboxylation of diversely functionalized aromatic carboxylic acids within 5-15 min. In the presence of at most 5 mol % of an inexpensive catalyst generated in situ from copper(I) oxide and 1,10-phenanthroline, even nonactivated benzoates were converted in high yields and with great preparative ease.
متن کاملSilver-catalysed protodecarboxylation of carboxylic acids.
A silver-based catalyst system has been discovered that effectively promotes the protodecarboxylation of various carboxylic acids at temperatures of 80-120 degrees C--more than 50 degrees C below those of the best known copper catalysts.
متن کاملDecarboxylative homocoupling of (hetero)aromatic carboxylic acids.
A variety of hetero(aromatic) carboxylic acids are shown to undergo decarboxylative homocoupling, mediated by a Pd/Ag system. This novel methodology for the synthesis of symmetrical biaryls avoids the use of haloarenes and organometallic compounds as starting materials.
متن کاملTransition Metal-Catalyzed Decarboxylative Coupling Reactions of Alkynyl Carboxylic Acids
The decarboxylative couplings of alkynyl carboxylic acids are an attractive area of research in organic chemistry, because the structure of aryl alkyne is one of the important building blocks for the synthesis of p-conjugated compounds. The use of alkynyl carboxylic acid as an alkyne source has several advantages in handling and storage. As a catalyst, palladium, copper, nickel, and silver were...
متن کاملPalladium-catalyzed decarboxylative coupling of aromatic acids with aryl halides or unactivated arenes using microwave heating.
Microwave heating greatly accelerates Pd-catalyzed decarboxylative coupling of aromatic acids and aryl iodides, and allows the coupling of benzoic acids with unactivated arenes.
