RESUMEN
The reactions of a cyclic alkyl(amino)carbene (CAAC)-stabilized beryllium radical with E2 Ph2 (E=S, Se, Te) and of a beryllole with HEPh (E=S, Se) yield the corresponding beryllium phenylchalcogenides, including the first structurally authenticated beryllium selenide and telluride complexes. Calculations show that their Be-E bonds are best described by the interaction between the Be+ and E- fragments, with Coulombic forces accounting for ca. 55 % of the attraction and orbital interactions dominated by the σ component.
