Catalytic cornerstone : Lanthanide( III ) complexes of a lacunary Dawson‐type polyoxometalate catalyze Lewis acid mediated reactions (see figure, TMS=trimethylsilyl). The compounds (NBu 4 ) 5 H 2 [α 1 ‐Ln(H 2 O) 4 P 2 W 17 O 61 ] (Ln=Yb, Sm, Eu, La) are much more chemoselective than the lanthanide triflates. Furthermore, the polyoxotungstic framework can play a role, presumably through H‐bonding to the substrates.
