✦ Synopsis

The silanediols RN(SiMe3)Si(OSiMe3)(0H)2 (R = 2,4,6-were characterized by means of mass, IR and NMR (lH and Me3C6H2 4, 2,6-Me2C6H3 5 , and 2,6-iPr2C6H3 6) were prepa-2gSi) spectroscopy. Additionally, the molecular structures of red by the reactions of the respective silanetriols RN(SiMe3)-4 and 7 were determined by single-crystal X-ray diffraction Si(0H)3 1-3 with SiMe3C1 in THF/hexane. Silanetriol 1 in studies. Compound 4 forms O-H-.O hydrogen-bonded te-CH,Cl,/hexane solution converts over a period of 4 weeks tramers in the solid state. A nine-membered ring formed by into the silanediol (2,4,6-Me3C,H,)N(SiMe,)Si(0SiMe2R)-an intermolecular 0-H-N hydrogen bond is found in the (OH), [R = CH2(2-NH,-3,5-Me,C6H2)] (7).
