Modellreaktionen zur Verankerung von Molybdän‐und Vanadium‐Oxiden auf Silicium‐Sauerstoff‐Oberflächen

Model Reactions to Anchor Molybdenum and Vanadium Oxides on Silica‐Oxygen Surfaces The eight‐and twelve‐membered ring compounds [( t Bu) 2 1‐Si(O) 2 MoO 2 ] 2 ( 1 ) and [( t Bu) 2 Si(O) 2 V(O)Cl] 3 ( 2 ) have been prepared by the reaction of di‐ tert 1‐butylsilanediol or its dilithium salt with MoO 2 Br 2 or VOCl 3 , respectively. Single crystal X‐ray structure analyses of 1 · 2 py and 2 have been performed. Crystals of 1 · 2 py contain two molecules of 1 · 2 py and four additional molecules of pyridine in the unit cell.
