Reversible Isomerizations between 1,4-Digermabenzenes and 1,4-Digerma-Dewar-Benzenes: Air-stable Activators for Small Molecules



Reversible Isomerizations between 1,4-Digermabenzenes and 1,4-Digerma-Dewar-Benzenes: Air-stable Activators for Small Molecules



Journal of the American Chemical Society 2019



The first examples of stable, crystalline, and air-sensitive 1,4-digermabenzenes were isolated. These species phtochemically isomerize into the corresponding air-stable digerma-Dewar-benzenes. An alkyl-substituted More importantly, these species photochemically isomerize into the corresponding air-stable digerma-Dewar-benzenes. The alkyl-substituted Dewar-type-1,4-digermabenzene can thus be considered as a "shelf-stable activator" for small molecules such as dihydrogen, carbon dioxide, and acetylene at room temperature, which can be thermally reactivated via a thermal retro-isomerization to afford the corresponding 1,4-digermabenzenes.
