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

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
Hamid Reza Khavasi et al.

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.

Journal of the American Chemical Society, 125(9), 2475-2479 (2003-02-27)
Quantum mechanical calculations were employed to predict the ratio of four stereoisomeric products expected from two complex reactions involving the aldol reactions of cyclohexanone with benzaldehyde or with isobutyraldehyde catalyzed by (S)-proline. Experimental tests of these predictions provide an assessment
