Germanium Analogue of the Parent Phosphine−Borane FLP Compound
Abstract Diimino−carbene‐supported germylone dimNHCGe does not react with BPh 3 and does not activate dihydrogen in the FLP mode in the combination with this borane. However, it reacts with B(C 6 F 5 ) 3 to give the zwitterionic borate dimNHCGe−(C 6 F 4 )BF(C 6 F 5 ) 2 . This compound can be convert...
