Vorschrift

For preparation of the silanol, 20 mmol 9-anthracenyl bromide are metallized with the equimolar amount of n-butyllithium (2 M solution in cyclohexane, 20 mmol) at −20° C. and dichlorodiphenylsilane is then added, in accordance with Example 2.1. When the addition of the dichlorodiphenylsilane has ended, the reaction mixture is heated under reflux for 3 h and then hydrolysed by addition of water (100 g).
