Abstract
The silanediols RN(SiMe3)Si(OSiMe3)(OH)2 (R = 2,4,6-Me3C6H24, 2,6-Me2C6H35, and 2,6-iPr2C6H36) were prepared by the reactions of the respective silanetriols RN(SiMe3)-Si(OH)31 - 3 with SiMe3Cl in THF/hexane. Silanetriol 1 in CH2Cl2/hexane solution converts over a period of 4 weeks into the silanediol (2,4,6-Me3C6H2)N(SiMe3)Si(OSiMe2 R)-(OH)2 [R = CH2(2-NH2-3,5-Me2C6H2)] (7). Compounds 4 - 7 were characterized by means of mass, IR and NMR (1H and 29Si) spectroscopy. Additionally, the molecular structures of 4 and 7 were determined by single-crystal X-ray diffraction studies. Compound 4 forms O-H...O hydrogen-bonded tetramers in the solid state. A nine-membered ring formed by an intermolecular O-H...N hydrogen bond is found in the solid-state structure of 7.
