Basic Research for Establishment of Functionalized Organosilicon Chemistry

(1)区域选择性合成多功能化烷基低硅烷在金属锂的促进下，四氢呋喃中的氨基二氯单硅烷与氯硅烷或氯二硅烷发生了高选择性的交叉偶联反应，高产率地生成了相应的对称和不对称氨基三硅烷。氨基转化为烷氧基或氟。(2)功能化硅孔和硅孔寡聚物的合成以1,1-二氨基硅孔为原料合成了一系列1,1-二功能化硅孔。寡聚（1,1-硅酮）s是一种通过硅链结的硅酮低聚物，已被合成为聚（1,1-硅酮）s的模型化合物。对晶体结构和紫外可见光谱进行了测定，其中特硅酮和季硅酮在280-290nm处具有独特的吸光度最大值。(3) Tris[2-（二甲氨基）苯基]硅烷和-日耳曼化合物的合成和结构合成了stris[2-（二甲氨基）苯基]硅烷和-日耳曼化合物，并用x射线晶体学对其进行了表征。氢硅烷和氢锗烷中的3个2-（二甲氨基）苯基包覆在硅和锗的氢原子上，使得硅- h和锗- h键变短，键的s性质增强。硅烷醇和日耳曼醇通过羟基和其中一个氨基之间的分子内氢键作为单体存在。

(1)Regioselective Synthesis of Polyfunctionalized AlkyloligosilanesHighly selective cross-coupling reactions promoted by lithium metal have been achieved between aminodichloromonosilanes and chlorosilanes or chlorodisilanes in THF to form the corresponding symmetrical and unsymmetrical aminotrisilanes in high yields. The amino group is converted to alkoxy group or fluorine.(2)Synthesis of Functionalized Siloles and Silole OligomersA series of 1,1-difunctionalized siloles have been synthesized from 1,1-diaminosiloles. Oligo (1,1-silole)s, silole oligomers catenated through silicons, have been synthesized as model compounds of poly (1,1-silole)s. Crystal structures and UV-vis spectra have been determined, in which tersilole and quatersilole have unique abdorption maxima around 280-290nm.(3)Synthesis and Structures of Tris [2-(dimethylamino) phenyl] silane and -germane CompoundsTris [2-(dimethylamino) phenyl] silane and -germane compounds were synthesized and charcterized by X-ray crastallography. Three 2-(dimethylamino) phenyl groups in the hydrosilane and hydrogermane encapsulate the hydrogen atom bonded to silicon and germanium, which results in the short Si-H and Ge-H bonds and an increase in the s character of the bonds. The silanol and germanol exist as monomers through the intramolecular hydrogen bonding between the hydroxy group and one of the amino groups.
