DIRECT OXIDATIVE AMINATION OF HYDROCARBONS

Provided is a process for converting a hydrocarbon comprising at least one C-H bond to a nitrogen-functionalized product. The process comprises contacting a hydrocarbon and (i) an oxidizing electrophile comprising (a) a main group element or transition metal in oxidized form and (b) at least one nitrogen-containing ligand, or (ii) an oxidant and a reduced form of an oxidizing electrophile comprising (a) a main group element or transition metal and (b) at least one nitrogen-containing ligand, in a solvent to provide the nitrogen-functionalized product and an electrophile reduction product. Further provided is an oxidizing composition comprising the oxidizing electrophile with at least one nitrogen-containing ligand and a non?oxidizable liquid.

Novel sterically hindered ferrocenyl-phosphonium salt

New sterically hindered ferrocenyl containing phosphonium salt was synthesized in two steps starting from ferrocene. To avoid halogen contamination di-tert-butylferrocenylphosphine was quaternized with methyl bis(trifluoromethanesulfonyl)imide directly. Obtained phosphonium salt was characterized with several physical methods.

Thermal degradation of ionic liquids at elevated temperatures

Ionic liquids based on the imidazolium cation are found to degrade, yielding volatile degradation products, at temperatures significantly lower than previously reported and thus a parameter Tz/x (the maximum operating temperature) is developed to provide a more appropriate estimate of thermal stability.
