Novel 1,3,5,7-tetrafluorocyclotetrasiloxanes were synthesized from cyclotetrasiloxanetetraol by a facile synthetic method. By adjusting the amount of the fluorinating reagent, synthesis of a single isomer of 1,3,5,7-tetrafluorocyclotetrasiloxanes as well as the preparation of all four isomers were accomplished. The products are expected to serve as potential precursors to not only well-defined silsesquioxanes but also asymmetric cyclic siloxanes.
采用简便的合成方法从环四硅四醇合成了新型的 1,3,5,7-四氟环四硅氧烷。通过调整氟化试剂的用量,合成了 1,3,5,7-四氟环四硅氧烷的单一异构体,并制备了所有四种异构体。预计这些产品不仅可以作为明确定义的硅倍半硅氧烷的潜在前体,还可以作为不对称环状硅氧烷的潜在前体。
