Novel germanium containing triflates were prepared from the reactions of trifluoromethanesulfonic acid with tetraphenylgermane (1) and digermanes (Ph3GeGeMe3 (4), Ph3GeGePh3 (5)). The improved procedures for synthesis of known organogermanium compounds (Ph4Ge (1), Ph3GeCl (2), Ph3GeGeMe3 (4), Ph3GeGePh3 (5)) were also presented. The crystal structure of Ph3GeOTf (6) and Ph2Ge(OTf)Ge(OTf)Ph 2 (7) was studied by X-ray analysis. In 7 each germanium atom is pentacoordinated due to intramolecular interaction with O atom of the neighboring triflate group.

Silylborates (Li[PhnMe3-nSiBPh3], n = 1-3) and germylborates (Li[PhnMe3-nGeBPh3], n = 1-3; M[Et3- GeBPh3], M = Li, Na, K) were prepared by the reaction of the corresponding silyl- and germylalkali metals with triphenylborane in a hexane/benzene mixed solvent. The silyl- and germylborates were fully identified by 1H, 13C, 11B, and 7Li NMR spectroscopic methods. The solid-state structure of germylborates Li[Ph3GeBPh3] and M[Et3GeBPh 3] (M = Li and Na) were determined by X-ray diffraction analyses. The polymeric structure of M[Et3GeBPh3] was observed in the solid state and in hydrocarbon solution. The alkali metal atoms were located near the center of the benzene ring of triphenylborane and interacted with the neighboring borate molecules by Li+-π interaction. The polymeric structure was broken by the addition of MeOH. However, M[Et 3GeBPh3] was coordinated by three MeOH molecules to form a dimeric structure without methanolysis reaction. The primary processes in photochemical reactions of silyl- and germylborates were investigated by chemical trapping experiments and the CIDEP (chemical-induced dynamic electron polarization) method. The cleavage of the Ge-B (or Si-B) bonds of germylborates (or silylborates) was considered most probably to occur from their triplet states.
