TL;DR: In this article, primary alcohols were converted into aldehydes by hydrogen transfer reaction using methyl vinyl ketone and ruthenium catalyst under microwave irradiation, which resulted in the recovery of the starting materials.

TL;DR: In this article, isoprene and its main degradation products, methyl vinyl ketone (MVK), methacrolein (MAC) and formaldehyde (HCHO), were measured in a Portuguese eucalyptus forest.

TL;DR: In this article, the rate constants for the OH + methyl vinyl ketone and methacrolein reactions have been measured in 2−5 Torr of He and over the temperature range 300−422 K using discharge-flow systems coupled with laser-induced fluorescence and resonance fluorescence detection of the OH radical.
Abstract: The rate constants for the OH + methyl vinyl ketone and OH + methacrolein reactions have been measured in 2−5 Torr of He and over the temperature range 300−422 K using discharge-flow systems coupled with laser-induced fluorescence and resonance fluorescence detection of the OH radical. The rate constant for the OH + methyl vinyl ketone reaction was found to be (1.73 ± 0.21) × 10-11 cm3 molecule-1 s-1 at 5 Torr. No significant pressure dependence was observed between 2 and 5 Torr at 300 K, but a pressure dependence of the rate constant was measured at temperatures between 328 and 422 K. At 328 K, the termolecular rate constant (k0) was measured to be (6.71 ± 2.65) × 10-28 cm6 molecule-2 s-1. An Arrhenius expression of k0 = (9.9 ± 7.6) × 10-30 exp[(1440 ± 300)/T] cm6 molecule-2 s-1 over the temperature range 328−422 K was obtained from a weighted linear least-squares fit of the k0 data versus temperature. Unlike the OH + methyl vinyl ketone reaction, a significant pressure dependence of the rate constant fo...

TL;DR: A convergent AB+CD synthesis of (±)daunomycinone 1 in 14% overall yield from hydroxy phthalan 10 is described in this paper, where methyl vinyl ketone reacts with 4,7-dimethoxy isobenzofuran (generated from 10 ) to provide the adduct 16 which is developed into the AB synthon 30.

TL;DR: Cycloadditions of vinylidenecyclopropanes with electron-deficient olefins, such as methyl vinyl ketone (MVK) and acrylaldehyde, proceed smoothly in the presence of a catalytic amount of triflic imide (Tf(2)NH) to give the corresponding functionalized cyclopentanes in good to high yields.
Abstract: [3+2] Cycloadditions of vinylidenecyclopropanes (VDCPs) with electron-deficient olefins, such as methyl vinyl ketone (MVK) and acrylaldehyde, proceed smoothly in the presence of a catalytic amount of triflic imide (Tf2NH) to give the corresponding functionalized cyclopentanes in good to high yields.
