CuSe2/CeO2 as a novel heterogeneous catalyst for reductive carbonylation of nitroarenes for generating urethanes

The reaction of CuCl2, SeO2, and cetyltrimethylammonium bromide (CTAB) under the CO pressure in methanol produce a black solid, which is identified as cupric diselenide, CuIISe2 using various spectroscopic analyses. Impregnation of 5 wt% of CuSe2 onto CeO2 resulted in much more enhanced catalytic activity due to the uniform and highly dispersed particle. The reductive carbonylation of nitrobenzene (NB) as a model substrate has been examined in the presence of the CuSe2/CeO2 as a single component heterogeneous catalyst, which is found to exhibit excellent catalytic activity for generating methyl-N-phenyl carbamate (MPC) in a highly selective fashion. The effects of various reaction parameters such as temperature, pressure, and reaction time have been investigated. A plausible reaction mechanism using this cheap heterogeneous catalyst is also presented, especially invoking the importance of CuSe2(μ-CO) species.

Synthesis and UV/Vis analysis of amino acid-derived bisurea-type receptors involving anion complexation

Sixteen new bisurea compounds incorporating versatile proteinogenic amino acids as well as nipecotic acid have been synthesized via addition reaction to aryl diisocyanates. The products were analytically characterized and their ability for anion recognition was studied by UV/Vis spectroscopy. In the presence of fluoride, acetate or dihydrogenphosphate ions, hyperchromic and bathochromic peak shifts were determined. By way of contrast, bromide, iodide, or hydrogensulfate ions cause no significant change of absorbance. The special effect of heterocyclic derivatives was explained by molecular modeling calculations. In addition, the crystal structure of the byproduct dimethyl N,N′-(1,4-phenylene)dicarbamate is discussed.

UFU ('Ullmann-Finkelstein-Ullmann'): a new multicomponent reaction

We developed conditions to carry out the first 'one-pot' Ullmann-Finkelstein-Ullmann multicomponent reaction reported. This reaction allows the one-pot synthesis of dissymmetrical para-disubstituted benzene scaffold from 1-bromo-4-iodobenzene and two N-nu
