A simple and efficient one-pot method for the preparation of aromatic iodides has been developed by sequential diazotization–iodination of aromatic amines employing sodium nitrite and sodium iodide in the presence of acidic ionic liquid N-methyl-2-pyrrolidonum hydrosulfate ([H-NMP]HSO4). The diazonium salts that are formed by this ionic liquid are stable at room temperature and r...

The carbonatation of semi-crystalline [ethylene – glycidyl methacrylate]-based polymers (Lotader® grades) was achieved using carbon dioxide as reagent and quaternary ammonium salts organocatalysts to form cyclic carbonate moieties on...

The secondary amine piperidine and the tertiary amine quinuclidine (l-azabicyclo[2.2.2]octane) were reacted in THF with one equivalent of triphenylphosphinegold(I) tetrafluoro­ borate, [Ph3PAu]+ BF4“, to give the monoaurated ammonium salts of formula [R„NHp_„)AuPPh3]+ BF4~ (n = 2, 3). The compounds were obtained as crystalline solids in good yields, and were characterized by IR and NM R spectro...
