of alkoxy(aminoalkyl)diorganylsilanes of the formula type R2(RO)Si(CH2)nNH2 (R = alkyl, n = 1–3) was conducted. For reasons of comparison, silanes of the formula types R2(RO)SiC(H)MeCH2NH2 and R2(RO)Si(CH2)nX [R = alkyl; n = 1–3; X = N(H)Me, NMe2, piperidino, NMe3+I–, N(H)COOMe, N(Me)COOMe] and compounds Me2(MeO)Si(CH2)6Me and Me2(MeO)Si(CH2)6NH2 were included in this study. For this purpose, the various
烷氧基(氨基烷基)硅烷是形成氨基官能化聚硅氧烷的重要前体,用于许多技术应用。为了更好地理解烷氧基(氨基烷基)硅烷的 Si-烷氧基部分的水解裂解机制(形成氨基官能化聚硅氧烷的重要关键步骤),对烷氧基(氨基烷基)水解的系统实验和计算研究进行了分子式为 R2(RO)Si(CH2)nNH2(R = 烷基,n = 1-3)的二有机基硅烷。出于比较的原因,分子式类型为 R2(RO)SiC(H)MeCH2NH2 和 R2(RO)Si(CH2)nX [R = 烷基;n = 1–3;X = N(H)Me、NMe2、哌啶基、NMe3+I–、N(H)COOMe、N(Me)COOMe] 和化合物 Me2(MeO)Si(CH2)6Me 和 Me2(MeO)Si(CH2)6NH2被纳入这项研究。以此目的,通过使用 1H NMR 光谱作为分析工具,合成了各种硅烷并研究了它们在酸性和碱性条件下在 CD3CN/D2O 中的
