Synthesis and structure of cyclotrigermenium salt of the tetrakis{3,5-bis(tri-fluoromethyl)phenyl}borate anion. A stable free germyl cation in the condensed phase

The reaction of tetrakis(tri-t-butylsilyl)cyclotrigermene with Ph3C+.[3,5-(CF3)(2)C6H3]B- (TFPB) and Ph3C+.(C6F5)(4)B- (TPFPB) in benzene produced the stable free tris(tri-t-butylsilyl)cyclotrigermenium ion (2a) with the corresponding tetraarylborate as a counter anion. The crystal structure of 2a T...

Summary:The reaction of tetrakis(tri-t-butylsilyl)cyclotrigermene with Ph3C+.[3,5-(CF3)(2)C6H3]B- (TFPB) and Ph3C+.(C6F5)(4)B- (TPFPB) in benzene produced the stable free tris(tri-t-butylsilyl)cyclotrigermenium ion (2a) with the corresponding tetraarylborate as a counter anion. The crystal structure of 2a TFPB reveals a free germyl cation with a 2a . electron system.
