Abstract
AbstractUsing the [3+2] cycloaddition reaction of [HC≡C−GePh2−]2 (1) and a number of RCH2N3, this work described the synthesis of a series of novel heterocyclic digermanes, bitriazoles [1,4‐C2HN3(CH2R)GePh2−]2, 2–12 (R=Ph, p‐Tol, p‐C6H4NMe2, p‐C6H4OMe, p‐C6H4Br, m‐C6H4NO2, 2‐Naphth, CH2‐p‐OC6H4CHO, CH2‐p‐OC6H4COOMe, CH2P(O)(OEt)2, COOEt), difficult to produce by other methods. The structural peculiarities of these compounds were studied in detail by NMR spectroscopy and by XRD analysis (for 6, 9 and 10). The properties of 1–12 were studied by UV/vis and luminescence emission spectroscopy, electrochemistry and DFT calculations, indicating an effective conjugation in their molecules.
