Equilibrium Acidities of Nitroalkanes in an Ionic Liquid

The acidity ladder scale in [BMPY][NTf2] was successfully expanded toward the weak acidity region for about five more pK units compared to the previously established one. This allows the acidities of a series of 13 aliphatic and aromatic nitroalkanes to be determined accurately by the UV-vis spectroscopic method. The acidity of nitroalkane in [BMPY][NTf2] covers ～8 pK units and is significantly weaker than those in DMSO and water. The Hammett plot for 4-substituted phenylnitromethanes shows an excellent linearity with a slope of 2.06, which is rather close to that in DMSO but significantly larger than that in water (0.80). The regression analyses reveal that the solvation behavior of [BMPY][NTf2] on the acidic dissociations of C-H acids is similar to that of DMSO.

SYNTHESIS OF 2-METHYLPROPENYL SULFIDES AND THEIR OXYGEN AND NITROGEN ANALOGS

Conditions were developed for the convinient preparative synthesis of 2-methylpropenyl sulfides and their oxygen and nitrogen analogs on the basis of reactions of thiols, alcohols, and lactams with isobutyraldehyde in excess of chlorotrimethylsilane.By-pr
