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
所述silanediols RN(森达3)的Si(OSiMe 3)(OH)2(R = 2,4,6-ME 3 c ^ 6 ħ 2 4,2,6-ME 2 ç 6 ħ 3 5,和2,6-我镨2 ç 6 ħ 3 6)由相应的硅烷三醇RN(森的反应制备3)-Si(OH)3 1 - 3与森达3氯在THF /己烷中。CH 2 Cl 2中的硅烷三醇1己烷溶液在4周内转化为硅烷二醇(2,4,6-Me 3 C 6 H 2)N(SiMe 3)Si(OSiMe 2 R)-(OH)2 [R = CH 2(2 -NH 2 -3,5-Me 2 C 6 H 2)](7)。化合物4-7通过质谱,IR和NMR(1 H和29 Si)光谱进行了表征。另外,通过单晶X射线衍射研究确定了4和7的分子结构。化合物4形成固态的OH…O氢键四聚体。在7的固态结构中发现了一个由分子间OH…N氢键形成的九元环。
