Ten 1-methyl-4-t-butyl-1-silacyclohexyl derivatives (C10H21Si–X, X=H, Cl, OCH(CH3)2, OCH3, OC(CH3)3, C6H5, p-Br–C6H4, p-Cl–C6H4, Si(CH3)2H, F) were synthesized and separated into conformationally stable cis and trans isomers. The stereochemistry of these compounds has been determined on the basis of NMR and GLC. They were found to behave stereochemically like acyclic optically active silanes.
合成了十种 1-甲基-4-叔丁基-1-硅杂环己基衍生物(C10H21Si-X,X=H、Cl、OCH(CH3)2、OCH3、OC(CH3)3、C6H5、p-Br-C6H4、p-Cl-C6H4、Si(CH3)2H、F),并将其分成构象稳定的顺式和反式异构体。根据核磁共振和气相色谱测定了这些化合物的立体化学性质。发现它们的立体化学行为类似于无环光活性硅烷。
