Abstract The reductivecoupling of aldehydes to afford pinacolic alcohols using all kinds of reducing agents involving samarium is well known. In this report, however, treatment of aromaticaldehydes with Cu(I)/Sm system produces benoins and/or benzils in good yields. A possible mechanism is proposed where Cu(I) not only activates the Sm metal but also promotes the dehydrogenation of the intermediates

imidazolium-based ionicliquids (TMICl @silica films) were prepared, characterized and utilized as efficient catalysts for the benzoin reaction. Combined characterization results from FT-IR, elemental analysis, N 2 adsorption–desorption isotherms and SEM, suggested that the imidazolium-based ionicliquids were successfully immobilized on the silica films. Moreover, the catalytic performance tests demonstrated

potent, bioavailable ACAT inhibitor may have beneficial effects in the treatment of atherosclerosis by (i) reducing the absorption of dietary cholesterol, (ii) reducing the secretion of very low density lipoproteins into plasma from the liver, and (iii) preventing the transformation of arterial macrophages into foam cells. We have found that a mevalonate derivative 2, which contains a 4,5-diphenyl-1H-imidazol-2-yl

Substitution at tetraaryl cyclopentadienones is known to affect the photophysical properties of the molecules. In a joint experimental and theoretical investigation, a series of differently substituted tetraaryl cyclopentadienones are studied upon so far unprecedented negative solvatochromic effect and, the impact of substituents on the electrochemical behavior.
