1,1,2,2-Tetraphenyldisilane-1,2-diol (3) was prepared in a two-step synthesis, starting from 1,2-bis(diethylamino)-1,1,2,2-tetraphenyldisilane (1). Treatment of 1 with acetyl chloride yielded 1,2-dichloro-1,1,2,2-tetraphenyldisilane (2), which upon hydrolysis gave 3 (total yield 83%). Compounds 2 and 3 were characterized by elemental analyses (C,H) and solution NMR experiments (1H, 13C, 29Si; CDCl3). In addition, compound 1 and its condensation product, 1,5-dihydroxy-1,1,2,2,4,4,5,5-octaphenyl-3-oxa-1,2,4,5-tetrasilapentane (4; studied as the hemibenzene solvate 4ּ1/2C6H6), were structurally characterized by single-crystal X-ray diffraction.
