Multigram amounts of [BeBr2(SMe2)2] (1) are quantitatively synthesized in a one pot synthesis by heating Be powder in a Br2 atmosphere and condensing Me2S on the formed BeBr2. The compound is very soluble e.g. in Me2S and CH2Cl2, loses Me2S under vacuum at 70 °C and is a versatile starting material for ether‐free homogenous reactions. 1 was characterized by X‐ray analysis, NMR and Raman spectroscopy, and used for the synthesis of (known) [BeCp2] and [Cp*BeBr].
