    • Reactivity of a Methylene‐Bridged 1,3‐Bis(germylene) in Dynamic Equilibrium with Its Dimer Peer-reviewed

      <jats:title>Abstract</jats:title><jats:p>We report the properties and reactivity of an unprecedented methylene‐bridged 1,3‐bis(germylene) derivative. In the solid state, it undergoes dimerization to afford a 1,2,4,5‐tetragermacyclohexa‐1,4‐diene derivative (Ge<jats:sub>4</jats:sub>CHD). Moreover, theoretical calculations on Ge<jats:sub>4</jats:sub>CHD reveal σ*–π interactions between the two π orbitals (Ge═Ge) and the CH σ* orbital. This interaction is confirmed by a significant red shift in the solid‐state UV–vis spectrum. In contrast to the behavior in the solid state, the Ge<jats:sub>4</jats:sub>CHD derivative dissociates in solution into a methylene‐bridged 1,3‐bis(germylene) derivative. The resultant 1,3‐bis(germylene) derivative reacted with S<jats:sub>8</jats:sub> to form a novel cage compound containing three S and two Ge atoms. On the other hand, in the reaction with triphenylphosphine sulfide, the in situ generated 2‐thia‐1,3‐digermabicyclo[1.1.0]butane derivative activated the benzene solvent, leading to the formation of a [2 + 2] cycloaddition product. Additionally, the 1,3‐bis(germylene) derivative reacted with 4‐dimethylaminopyridine (DMAP) to form a three‐membered ring. Its structural parameters and the results of theoretical calculations indicated the zwitterionic character.</jats:p>

    • Synthesis of Novel Imido-substituted 1,4-Naphthoquinones and Benzoquinone derivatives Peer-reviewed

      <jats:p>Imido-substituted 2-bromo-1,4-naphthoquinones and benzoquinone have been formed from quinones and N-bromosuccinimide in the presence of DABCO under mild conditions. The reaction seems to proceed through partially radical pathway based on control experiments. Nucleophilic addition-elimination of imidated quinones have occurred smoothly to provide new class of substituted quinone derivatives in good yields. </jats:p>

    • A Unique Synthetic Route toward a 1,2‐Dihydrodigermene via Formal α‐Elimination of Bromo and Silyl Groups from a Bromo(phenylsilyl)germane Peer-reviewed

      <jats:title>Abstract</jats:title><jats:p>A 1,2‐dihydrodigermene bearing Tbb {4‐<jats:italic>t</jats:italic>‐butyl‐1,3‐bis[bis(trimethylsilyl)methyl]phenyl} groups was successfully synthesized and isolated <jats:italic>via</jats:italic> formal <jats:italic>α</jats:italic>‐elimination of bromo and silyl groups from the corresponding Tbb‐substituted boromo(phenylsilyl)germane. This novel synthetic method is conducted under mild conditions, representing a significant advantage in the field concerned. The synthesized 1,2‐dihydrodigermene was characterized by NMR spectroscopy, mass spectrometry, and single‐crystal X‐ray crystallography. In the <jats:sup>1</jats:sup>H NMR spectrum, the Ge−<jats:styled-content>H</jats:styled-content> unit was found to be less electronically affected from the substituents compared to that of the previously reported 1,2‐dihydrodigermene. Moreover, the UV/vis spectra at various temperatures indicated the formation of the isomeric (dihydrogermyl)germylene. In fact, the 1,2‐dihydrodigermene once isolated reacted with DMAP in solution to afford the corresponding complex of the (dihydrogermyl)germylene.</jats:p>
