IN THE CRYSTAL STRUCTURE OF THE TITLE COMPOUND [SYSTEMATIC NAME: 1-(2-hy-droxy-eth-yl)-2-methyl-5-nitro-1H-imidazol-3-ium perchlorate], C(6)H(10)N(3)O(3) (+)·ClO(4) (-), the cations are linked by inter-molecular N-H⋯O hydrogen bonds into zigzag chains along the c axis. The cations and anions are connected by O-H⋯O and C-H⋯O hydrogen bonds. A weak intra-molecular C-H⋯O hydrogen bond is also obse...

A NiCl(2)-6H(2)O/Zn reagent with a 2-aryliminomethylpyridine ligand catalyzed cyclization/polymerization of 1,6-diynes to yield mainly the corresponding poly(1,3-butadienylene) compounds, whereas NiBr(2)-3H(2)O/Zn with the use of 3-(2-(2-methoxyethoxy)-ethyl)-1-methyl-1H-imidazol-3-ium bromide as a ligand converted 1,6-diynes to the corresponding annulated 1,3,5,7-cyclooctatetraenes in a biphas...

An environmentally benign procedure for the synthesis of vicinal nitrohydrins via the regioselective ring opening reaction of epoxides with nitrite anion using silica-bound 3-{2-[poly(ethylene glycol)]ethyl}-substituted 1-methyl-1H-imidazol-3-ium bromide as an effective heterogeneous phase transfer catalyst was described. Short reaction time, high yield of products, simple work-up proc...
