Graphical Abstract
One gold is enough: Mononuclear, homogeneous gold catalysts displayed excellent catalytic activity on the order of that previously reported for gold nanoparticle catalysts and surface-bound gold complexes. In the model synthesis of spiro compounds (see picture) extremely high turnover numbers were achieved with only 0.000001 mol % of a silsesquioxane-substituted catalyst.

- 21The stock solutions were prepared by stepwise dilution in volumentric flasks. According to the analysis by ICP (inductively coupled plasma), for example, the lowest concentration sample, which was 0.000001 M in catalyst (which is 1.3764 mg L−1 of catalyst and should correspond to 196.97 μg L−1 of gold), showed 188 μg L−1 (the detection limit of the instrument was 1.7 μg L−1, measuring limit 5.3 μg L−1); when another 100 μg L−1 was added to this sample, the value measured as expected was 291 μg L−1.
