Abstract

The reaction of the bulky EMind-based diarylgermylene, (EMind)₂Ge: (1a) (EMind = 1,1,7,7-tetraethyl-3,3,5,5-tetra-methyl-s-hydrindacen-4-yl), with pyridine N-oxide (Py⁺O¹) initially formed the Py-coordinated diarylgermanone, (EMind)₂Ge(=O)(Py) (3a), which gradually converted to the 1,3,2,4-dioxadigermetane, (EMind)₄Ge₂(μ-O)₂ (4a), through the dimerization of the germanone, (EMind)₂Ge=O (2a). The Ge=O double-bond in 3a reacted not only with H₂O to give the germanediol, (EMind)₂Ge(OH)₂ (5a), but also with Py⁺O¹ to form the germanol, (EMind)₂Ge(C₅H₄NO)(OH) (6a), via activation of the ortho CH bond.
