Some aspects of chemistry of the N→Si chelated aryloxydihydrosilanes R(ArO)SiH2(RPh, ArO) and of the 2,2-diaryloxytrisilane (Me3Si)2Si(OAr)2{ArO2,4,6-[(CH3)2NCH2]3C6H2O}

trimethylsilyltriflate or iodine yielded the novel stable silicenium ion [(ArO)2(H)Si]+X−. Reactions of 2 with sulfur S8 and the transition metal complex Fe(CO)5 have resulted in the isolation of the new complexes (ArO)2SiE [E=S, Fe(CO)4]. Decomposition modes of the tetracoordinate 2,2-diaryloxytrisilane (Me3Si)2Si(OAr)2 (3) on thermolysis and photolysis have also been studied; two pathways involving
五配位芳氧基二氢硅烷Ph(ArO)SiH 2(1)与羟基,羰基衍生物和PCl 5的反应导致形成新的烷氧基化,苯氧基化和卤代氢硅烷Ph(ArO)(H)X(X = Cl,OR,OAr ,OC(O)R)。用N-氯代或N-溴代琥珀酰亚胺,三甲基甲硅烷基三氟甲磺酸盐或碘对六配位(4 + 2)二芳氧基二氢硅烷(ArO)2 SiH 2(2)进行处理,得到了新型稳定的硅离子[[ArO)2(H)Si] + X -。2的反应与硫(S)8和过渡金属络合物的Fe(CO)5已导致新的复合物(ARO)的隔离2 SiE[E = S,铁(CO)4 ]。还研究了四配位的2,2-二芳氧基三硅烷(Me 3 Si)2 Si(OAr)2(3)在热解和光解下的分解模式;通过捕获实验确定了涉及形成两个亚甲硅烷基(ArO)(Me 3 Si):和(ArO)2 Si:的两条途径。
