Research output: Contribution to journalArticlepeer-review


The previously unknown dianionic species with exocyclic structures were synthesized by the reaction of the corresponding cyclic acylgermanes with 2.1 equivalence of KOtBu. The structural properties of the resulting products were analyzed by a combination of NMR and UV-​visible absorption spectroscopy, single X-​ray crystallog., and d. functional theory quantum chem. calcns., and it has been found that and are best described by the keto-​form (resonance structure I) in soln. as well as in the solid state. The reactivity of and toward a variety of selected electrophiles was also examd.
