	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.},

Both compounds gave nearly identical IR and Raman spectra, which suggests a cis-square-planar configuration. The average CO stretching frequencies were at 2217 and 2201 cm-1 for Pd(CO)2(SO3F)2 and Pt(CO)2(SO3F)2, respectively. They are unusually high and suggest substantially reduced pi-back-donation.

The resulting products are white hygroscopic solids which are not sufficiently soluble in HSO3F to allow electrical conductivity and NMR studies or Hammett acidity function (H-0) determinations in order to evaluate their use as Lewis acids in conjugate superacid systems. Oxidation of titanium under similar conditions resulted in the formation of a greenish-yellow resin-like material of limited thermal stability with the approximate composition Ti(SO3F)4. However, infrared spectra indicated the presence of small amounts of HSO3F. In addition, the solvolysis of ZrCl4 in an excess of HSO3F at 25-degrees-C has been investigated as a potential route to Zr(SO3F)4. The results indicate that short reaction times of 1-2 d yielded incompletely substituted products of the approximate composition ZrClx(SO3F)4-x (x = 0.22), while prolonged reaction times of 3-4 weeks gave rise to partially decomposed materials of approximate composition ZrO0.5F1.5(SO3F)1.5. The ability of all three tetrakis(fluorosulfato) metallates to act as SO3F- ion acceptors is evident from the isolation of thermally stable salts of the composition Cs2[M(SO3F)6] (M = Ti, Zr or Hf) when the metal oxidation was carried out in the presence of 2 mol equiv. of CsSO3F. All the materials were characterized by their vibrational spectra, which are extremely similar and closely resemble those of previously reported cesium hexakis(fluorosulfato) metallates.},

All substrates reacted exothermically, and sometimes explosively, between 80-298 K. The presence of the byproducts obtained may be rationalized by the thermal decomposition of some of the FOSO2F, which proceeds along two pathways, i.e. FOSO2F {\textendash}> 1/2O2 + SO2F2 and FOSO2F {\textendash}> 1/2F2 + 1/2S2O6F2, during the extremely exothermic reactions via radical intermediates. The fluorine formed gives rise to fully fluorinated products, and the SO3F. radicals, initially formed, either dimerize to give S2O6F2 or decompose to O2 and S2O5F2. Element fluoride-fluorosulfates, when formed at all, were obtained in low yields only when SO2F2 or SO2FCl were used as suitable moderators. The complete vibrational spectra of EF5OSO2F (E = S, Se or Te) have been studied and assigned. The reactions of I2, Br2 and AsF3 with FOSO2F yielded viscous liquids of the approximate, non-stoichiometric composition EFn(SO5F)5-n (E = As or I) and EFn(SO3F)3-n (E = Br), with n = non-integral number. All compounds were characterized by their vibrational and F-19 NMR spectra, and in the case of SeF5OSO2F by Se-77 NMR methods.},
