Cover Feature: Reactivity of the Bicyclic Amido‐Substituted Silicon(I) Ring Compound Si4{N(SiMe3)Mes}4 with FLP‐Type Character (Chem. Eur. J. 69/2021)

The unsaturated bicyclo[1.1.0]tetrasilatetraamide Si4{N(Mes)SiMe3}4 shown in the upper right corner has two threefold‐coordinated silicon atoms that show zwitterionic character. This gives the molecule intramolecular FLP‐type character. Different acids such as AlBr3, BH3, H+ and the base NHCMe4 can...

Description
Summary:The unsaturated bicyclo[1.1.0]tetrasilatetraamide Si4{N(Mes)SiMe3}4 shown in the upper right corner has two threefold‐coordinated silicon atoms that show zwitterionic character. This gives the molecule intramolecular FLP‐type character. Different acids such as AlBr3, BH3, H+ and the base NHCMe4 can simply coordinate to the threefold‐coordinated silicon atoms. These reagents “click” in place just like magnetic sticks and steel balls from a molecular construction kit do. More information can be found in the Full Paper by F. Lips et al.
