The reaction of 2-aminothiazoles with ethyl acetoacetate in acetic or polyphosphoric acid gave a series of 5H-[1,3]thiazolo[3,2-a]pyrimidin-5-one derivatives which were nitrated with a mixture of nitric and sulfuric acid to 6-nitro-5H-[1,3]thiazolo[3,2-a]pyrimidin-5-ones, and the latter were reduced to the corresponding amines. © 2013 Pleiades Publishing, Ltd.

Synthesis of tetrafluoroethane-β-sultone by the reaction of tetrafluoroethylene with sulfuric anhydride and of fluorocarbonyldifluoromethanesulfonyl fluoride by catalytic reaction of tetrafluoroethylene with sulfuric anhydride using BAU-2, SKT-6, or AG-3 activated carbon as catalyst was studied. The possibility of replacing sulfuric anhydride prepared by distillation from oleum by sulfuric anhydride prepared by sulfur dioxide oxidation was demonstrated. © 2014 Pleiades Publishing, Ltd.
