摘要：Homoleptic σ-bonded metal carbonyl cations (σ-carbonyls) and their derivatives have grown in recent years into a large subgroup of mononuclear metal carbonyl complexes. They are at prent formed by 17 elements, including the post transition metal mercury. Most are generated in superacids: the Lewis superacid SbF5 and the conjugate BrnstedLewis superacid HFSbF5. Thermally stable salts are formed with the superacid anions [Sb2F11]- and [SbF6]-. Many of the cations are superelectrophilic, with metals in oxidation states of +2 or +3. Three different synthetic routes are devel
oped: reductive (A) or solvolytic carbonylations (B) and oxidative methods (C). Considerable progress has been made by replacing the Lewis superacid SbF5 as reaction medium by the conjugate BrnstedLewis superacid HFSbF5. This allows reactions to proceed faster 二母宁嗽丸
