<jats:title>Abstract</jats:title><jats:p>Diphenylberyllium [Be<jats:sub>3</jats:sub>Ph<jats:sub>6</jats:sub>] is shown here to react cleanly as a Brønsted base with a vast variety of protic compounds. Through the addition of the simple molecules <jats:italic>t</jats:italic>BuOH, HNPh<jats:sub>2</jats:sub> and HPPh<jats:sub>2</jats:sub>, as well as the more complex 1,3‐bis‐(2,6‐diisopropylphenyl)imidazolinium chloride, one or two phenyl groups in diphenylberyllium were protonated. As a result, the long‐postulated structures of [Be<jats:sub>3</jats:sub>(O<jats:italic>t</jats:italic>Bu)<jats:sub>6</jats:sub>] and [Be(μ‐NPh<jats:sub>2</jats:sub>)Ph]<jats:sub>2</jats:sub> have finally been verified and shown to be static in solution. Additionally [Be(μ‐PPh<jats:sub>2</jats:sub>)(HPPh<jats:sub>2</jats:sub>)Ph]<jats:sub>2</jats:sub> was generated, which is only the second beryllium‐phospanide to be prepared; the stark differences between its behaviour and that of the analogous amide were also examined. The first crystalline example of a beryllium Grignard reagent with a non‐bulky aryl group has also been prepared; it is stabilised with an N‐heterocyclic carbene.</jats:p>
