Abstract

A cyclic (alkyl)(amino)germylene undergoes a ring expansion reaction with dibromomesitylborane (MesBBr₂) to afford a six-membered dibromogermane derivative. In the presence of Lewis bases (PMe₃ or ^MeNHC), reduction of the latter with two equivalents of potassium graphite (KC₈) gives rise to cyclic (alkyl)(boryl)germylene–Lewis base adducts. Upon heating, the germylene—PMe₃ adduct reacts with H₂ to yield a germane, probably via a base-free germylene featuring a small HOMO–LUMO gap.
