POLYOXO COMPOUNDS

One of the significant differences between sulfur and oxygen chemistry is the relnctance of oxygen to form long chains of the type RO—0 —OR (n 0, R,R = H, alkyl, aryl). The earliest reports on the preparation and characterization of the smallest polyoxo compound H2O3 dates back to 1963. The synthesis, structural characterization and exploration of this chemistry has made tremendous progress within the last decades and has opened a new area in peroxide chemistry, which is associated with the qnestion on the maxi-mnm possible chain length of a polyoxide chain before the system escapes spectroscopic characterization based on its lability .
