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.
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 [...

A robust allylic palladium-NHC complex was developed and exhibited extremely high catalytic activity toward aminocarbonylation of various (hetero)aryl iodides under atmospheric carbon monoxide pressure, in which a broad range of secondary and primary amines were well tolerated. In addition, the concise synthesis of an anticancer drug tamibarotene was accomplished even in a gram scale, further highlighting the practical applicability of the protocol.
