Thiiranium salts [Ad2SR]+X− (5, 8, 9, 11, 12; X−=Tf2N− (Tf=CF3SO2), SbCl6−) and seleniranium salts [Ad2SeR]+X− (14, 16, 17, 23–25; X−=Tf2N−, BF4−, CHB11Cl11−, SbCl6−) are synthesized from strained alkene bis(adamantylidene) (1). The disulfides and the diselenides (Me3SiCH2CH2E)2 (4, 13), (tBuMe2SiCH2CH2E)2 (7, 22), and (NCCH2CH2E)2 (10, 15; E=S, Se) have been used. The thiirenium salts [tBu2C2SR]+X−
