Procedure

The oxidation of the tris(9-anthracenyl)silane is carried out analogously to Example 1.1 with 5 molar equivalents of potassium permanganate in boiling tetrahydrofuran. The reaction is interrupted after 15 h and, after filtration over silica gel to separate off pyrolusite from the solution, the silanol formed is obtained as a yellowish solid by concentration of the reaction mixture, yield: 10.75 g with a purity of 85% (GC-MS). Further purification is carried out by crystallization from boiling ethanol.
