9-Aluminafluorenes have only been sparingly investigated and their properties still remain largely unexplored. Herein, we report the synthesis of five aluminafluorene derivatives with a diverse array of aluminium substituents and probe their Lewis ac

Aside from simple Lewis acid-base chemistry, the reaction chemistry of aluminacyclopentadienes, which are commonly referred to as aluminoles or simply alumoles, remains relatively underdeveloped. To date, few attempts to extend their inherent inserti

A doubly cyclic (alkyl)(amino)carbene-stabilised dihydroboronium cation undergoes fully reversible 2e– reduction to a stable hydroboryl anion via B-to-C hydrogen migration. Subsequent 1e– oxidation yields a bench-stable neutral hydroboryl radical

The chemistry of aluminacyclopentadienes, also known as alumoles, has experienced a resurgence in recent years, resulting in the preparation of a number of new entries in this class of compound. In contrast, their reactivity remains relatively unexpl

A new structural class of boron-based diradicals is prepared by Lewis base addition to and reduction of singly cyclic (alkyl)(amino)carbene (CAAC) stabilised diborylalkenes. The diradicals feature a perpendicular olefinic bridge preventing delocaliza
