Seleniranium salts [Ad 2 SeR] + X − ( 2 – 8 ), which are moderately stable at room temperature, were synthesized by addition of RSe + X − equivalents to the bulky olefin bis(adamantylidene) Ad=Ad ( 1 ), where R is aryl or alkyl and X − is Tf 2 N − , B(C 6 F 5 ) 4 − , or SbCl 6 − . Unstable telluriranium salts [Ad 2 TeR] + X − ( 9 – 12 ) were obtained by addition of RTe + X − equivalents to 1 (R=Ph, Et; X − =Tf 2 N − , BF 4 − ). The compounds were characterized by NMR spectroscopy and quantum chemical calculations, and the Se compounds also by ESI mass spectrometry. Crystal structures were determined for seleniranium salts 2 and 7 and telluriranium salt 9 .
