Highly efficient isobutyraldehyde-mediated epoxidation of cyclic alkenes with dioxygen catalyzed by a novel dimeric manganese(II) complex containing an easy-to-prepare flexible carboxamide ligand.

Hamid Reza Khavasi et al.

Inorganic chemistry, 48(13), 5593-5595 (2009-05-28)

Dioxygen epoxidation of cyclic alkenes into their corresponding epoxides was successfully achieved in good yield by using a novel binuclear manganese carboxamide complex as the catalyst and isobutyraldehyde as the cosubstrate.

Use of gas chromatography-olfactometry to identify key odorant compounds in dark chocolate. Comparison of samples before and after conching.

Christine Counet et al.

Journal of agricultural and food chemistry, 50(8), 2385-2391 (2002-04-04)

After vacuum distillation and liquid-liquid extraction, the volatile fractions of dark chocolates were analyzed by gas chromatography-olfactometry and gas chromatography-mass spectrometry. Aroma extract dilution analysis revealed the presence of 33 potent odorants in the neutral/basic fraction. Three of these had

Energy-gaining formation and catalytic behavior of active structures in a SiO(2)-supported unsaturated Ru complex catalyst for alkene epoxidation by DFT calculations.

Rudy Coquet et al.

Physical chemistry chemical physics : PCCP, 9(45), 6040-6046 (2007-11-16)

The formation and catalytic behavior of active structures in a SiO(2)-supported unsaturated Ru complex catalyst for alkene epoxidation were studied by means of hybrid density functional theory (DFT) calculations. An energy-gaining route for the catalyst activation was found to allow

Organocatalytic enantioselective cross-aldol reactions of aldehydes with isatins: formation of two contiguous quaternary centered 3-substituted 3-hydroxyindol-2-ones.

Fei Xue et al.

Chemistry, an Asian journal, 4(11), 1664-1667 (2009-09-12)

Stereospecific synthesis of alkyl-substituted vicinal diamines from the mother diamine: overcoming the "intrinsic barrier" to the diaza-Cope rearrangement reaction.

Hyunwoo Kim et al.

Organic letters, 11(1), 157-160 (2008-12-10)

Addition of isobutyraldehyde to 1,2-bis(2-hydroxyphenyl)-1,2-diaminoethane (mother diamine) cleanly gives a stable, fused imidazolidine-dihydro-1,3-oxazine ring complex. However, vigorous heating of the fused ring complex gives the diaza-Cope rearrangement product with excellent yield and stereoselectivity. A variety of alkyl aldehydes have been
