摘要：

(Chemical Equation Presented) The key to the general and efficient palladium-catalyzed formylation of aryl and heteroaryl bromides is the use of the di-1-adamantyl-n-butylphosphane (cataC-Xium A) as ligand. Low pressure of the synthesis gas and appropriate choice of the base are also important for high yields (up to 99%) of a broad range of (hetero)aromatic aldehydes at unprecedented low catalyst concentrations (see scheme; TMEDA= N,N,N′,N′-tetramethylethylenediamine). © 2006 Wiley-VCH Verlag GmbH & Co.
