For the first time, we have successfully applied Co2(CO)8 as an effective carbonyl source for the Pd catalysed alkoxycarbonylation of aryl halides affording the corresponding aryl esters under mild microwave conditions. A wide variety of esters and carbonyl derivatives were prepared using this protocol.

palladium-catalyzed carbonylation of aryl, alkenyl, and allyl halides with phenyl formate is reported. This procedure does not use carbon monoxide and affords one-carbon-elongated carboxylic acid phenyl esters in excellent yields. The reaction proceeds smoothly under mild conditions and tolerates a wide range of functional groups including aldehyde, ether, ketone, ester, and cyano groups. Furthermore, a variety

Mo(CO)6-mediates the alkoxycarbonylation of arylhalides in their reaction with alcohols to afford arenecarboxylic acid esters. The molybdenum carbonyl complexes act as the catalyst and the source with carbon monoxide. The alkoxycarbonylation proceeds with a small excess of carbon monoxide in the form of Mo(CO)6 and the procedure is simple compared to the conventional method, which uses palladium catalyst
Bis(cyclopentadienyldicarbonyliron) as a Convenient Carbon Monoxide Source in Palladium-catalyzed Carbonylative Coupling of Aryl Iodides with Amines, Alcohols, and Thiols
Bis(cyclopentadienyldicarbonyliron) ([CpFe(CO)2]2) serves as a carbon monoxide source in carbonylativecouplingreactions. Treatment of aryliodides with primary amines in the presence of DBU and [...

Thermoplastic elastomer compositions comprise a blend of polyester resin and a covalently-crosslinked acrylate rubber. Such compositions can be prepared by dynamic vulcanization of the rubber in admixture with the polyester and can exhibit high temperature dimensional stability and low oil swell.
