1-butyl-3-methylimidazolium bromide ([bmim]br) as an ionic liquid promoted selectively oxidation of aliphatic and aromatic sulfides to the corresponding sulfoxides and the oxidative coupling of thiols to disulfides by nabro3 in excellent yields under neutral conditions.

In the present study, the effects of calcium doping on the performance of the co-precipitated Cu-MgO catalysts prepared with different calcium loadings in the selective hydrogenation of furfuraldehyde were investigated. The results proved that the addition of this promoter had a remarkable impact on the catalytic performance. The conversion of furfuraldehyde enhanced up to 83% and the furfuryl ...

This paper examines the hypothesis that greater job status makes a person healthier. It begins by successfully replicating the well-known cross-section association between health and job seniority. Then, however, it turns to longitudinal patterns. Worryingly for the hypothesis, the data-on a large sample of randomly selected British workers through time-suggest that people who start with good h...

A mild and efficient one-pot visible light-induced method has been developed for the allylic oxidation. The oxidation of allylic systems has played a prominent role in this context as possibly the most widely applied C–H functionalization, owing to the utility of enones. The allylic C–H oxidation is relatively simple and predictable, even on a preparative scale, because active species generated...

Replacement of lysine 72 in RecA protein with arginine produces a mutant protein that binds but does not hydrolyze ATP. The protein nevertheless promotes DNA strand exchange (Rehrauer, W. M., and Kowalczykowski, S. C. (1993) J. Biol. Chem. 268, 1292–1297). With RecA K72R protein, the formation of the hybrid DNA product of strand exchange is greatly affected by the concentration of Mg in ways th...
