Abstract
The complex [(PPh3)Ag(CB11H6Br6)] 1 is an effective and selective catalyst (0.1 mol% loading) for a hetero-Diels-Alder reaction, which shows a marked dependence on the presence of trace amounts of water, while addition of Ag[ Y] [Y = CB11H12, CB11H6Br6, O3SCF3] to a phosphine functionalised support g ives an efficient and recyclable Lewis acid catalyst for this transformatio n.
