Abstract

Olefin π-complexes of divalent palladium are well known to react with nucleophilic reagents [1]. In the presence of suitable reoxidant the process can be made catalytic in palladium; this reaction, known as 'Wacker oxidation' [2], has significant value in organic chemistry [3]. Substrates, having both double bond and nuclephilic group in the same molecule, react in the intramolecular fashion, forming heterocycles 1 and 4. Specifically, Murahashi et al. have ...
