硅三环系列(Silatrane)和硼三环(Boratrane)属于一类在结构和应用上都很有意义的三环化合物(图1)。许多实验事实都已证实了在硅三环系列的氮、硅间和硼三环中氮、硼间成键,因此硅、硼在该类化合物中的价态异于通常,这就使得这些键的本质与成因成了研究者注视的焦点。 Silatrane and Boratrane belong to a class of tricyclic compounds both structurally and practically useful (Figure 1). Many experimental facts have proved that nitrogen and boron in silicon tricyclic series nitrogen, silicon and boron tricyclic nitrogen and boron bond, so silicon, boron valence in the class of compounds is different from the usual, which makes these bonds The nature and causes of researchers became the focus of attention.
