	abstract = {{Two types of highly electrophilic cations, {\textquoteright}bare{\textquoteright} M(2+) or carbonyl cations, formed by the noble metals palladium and platinum (Group 10) and silver and gold (Group 11) in low oxidation states (+1 or +2) are generated in highly acidic media. The acidic media consists of: the Bronsted superacid HSO3F; the Lewis superacid SbF5; and the conjugate superacid HSO3F-SbF5. Derived from these superacids are the very weakly nucleophilic anions SO3F- or Sb2F11- as counterions to stabilize the cations in solids. Finally, stabilization of the highly electrophilic cations by coordination to CO leads to isolable complexes, unprecedented in transition-metal chemistry in their structural, spectroscopic and bonding characteristics. The cations discussed include, in addition to {\textquoteright}bare{\textquoteright} M(2+) (M=Ag or Au): linear [M(CO)(n)](+)},

	abstract = {In addition to the numerous and varied examples of organometallic and coordination compounds where carbon monoxide functions as a pi-acceptor ligand, there is a small but select group of derivatives where the CO-metal bonding relies predominantly on a-bonding only. The metal derivatives, which include Pt(CO)(2)Cl-2 known since 1868, are formed by electron-rich metals (Pd, Pt, Ag and Au), in oxidation states +1 and +2, are cationic in nature, and are for the most part thermally stable. Their generation in strong protonic and Lewis acids (HSO3F, HSO3F-SbF5 and liquid SbF5) allows convenient synthesis. The predominance of sigma-bonding results in unusual spectroscopic properties, such as <(nu)over bar>CO stretching vibrations as high as 2280 cm(-1), relative to 2143 cm(-1) in free CO, and C-13 chemical shifts which are 180-130 ppm rather than 190-220 ppm for classical transition-metal carbonyls. Consequently two basic principles, the synergic bonding model and the rule of 18, fail for these complexes. Recent structural studies point to the importance of secondary OC...OS or OC...FSb contacts, which in place of pi-backdonation provide for a measure of charge compensation both in solution or in the solid state. This review concentrates on very recent (since 1990) developments in this field, which is expanding rapidly beyond the transition metals.},

	abstract = {X-ray photoelectron spectra of the first-stage acceptor graphite intercalation compounds C7SO3F, C14SO3F.HSO3F, C12SO3CF3, and C8SbF6 are reported. The carbon is core electron binding energy is shifted to slightly lower energies relative to graphite for all four acceptor GICs, largely on account of a Fermi level shift to lower energy upon oxidative intercalation. The shifts in binding energies for the C 1s core electron are compared to those of various fluorinated graphites and to shifts reported previously for related acceptor GICs. In addition, the O 1s, F 1s, and S 2p3/2 XPS spectra are reported. Comparison to those of simple ionic salts formed by the intercalate anions allows an estimation of the Fermi level shift in the acceptor GICs.},
