Abstract:
Diimino-carbene-supported germylone dimNHCGe does not react with BPh3 and does not activate dihydrogen in the FLP mode in the combination with this borane. However, it reacts with B(C6 F5 )3 to give the zwitterionic borate dimNHCGe-(C6 F4 )BF(C6 F5 )2 . This compound can be converted into the hydroborate dimNHCGe-(C6 F4 )BH(C6 F5 )2 (8) and further into [dimNHCGe-(C6 F4 )B(C6 F5 )2 ]+ (4). Compound 4 is a Ge/B analogue of Stephan's FLP parent P/B compound (C6 H2 Me3 )2 P-C6 F4 -B(C6 F5 )2 but unlike the latter cannot split dihydrogen. Moreover, attempts to prepare a Ge/B analogue of the zwitterion (C6 H2 Me3 )2 HP-C6 F4 -BH(C6 F5 )2 by protonation of borate 8 resulted in immediate elimination of H2.
