Alkanes manganese salts

The insertion of oxygen into a C-H-bond via allylic oxidation or alkane oxidation is a difficult reaction and not many efficient methods are known in the literature [32]. Recently, a fluorinated manganese catalyst solubilized in a perfluorinated solvent has found application in the oxidation of cyclohexene to cyclo-hexenol and cyclohexenone [33, 34]. As catalyst precursor the manganese salt of... 

Applications. In 1994 ca. 305 10 " t of liquid sulfur dioxide was consumed just in the USA, of which 40% was utilized in the manufacture of sulfur-containing chemicals such as sulfites, hydrogen sulfites, thiosulfites, dithionites and salts of hydroxyalkane sulfinic acid and alkane sulfonates. It is also utilized in cellulose manufacture, in the chemical dressing of manganese ores, in the removal of sulfur-containing impurities from mineral oils, for disinfection and preservation in the food industry and for the treatment of water. 

Recently, a highly efficient alkane oxidation has been described [15p,q, 22] for the system consisting of hydrogen peroxide, the manganese(lV) salt [L2Mn203](PF6)2 (X-1) (L = l,4,7-trimethyl-l,4-7-triazacyclononane) as the catalyst, and a carboxyhc acid as an obligatory component of the reaction mixture (Scheme X.7).
