title: Self-buffering hybrid gold-polyoxometalate catalysts for the catalytic cyclization of acid-sensitive substrates.
abstract: Grafting of a gold complex to an organo-polyoxometalate delivers catalytically active bitopic hybrids. The gold end activates allenes, while the metal-oxide surface can capture protons (see scheme). The scope of the gold-catalyzed oxacyclization of allenols is expanded to highly sensitive tertiary benzylic alcohols.
