TL;DR: Dialkylborane catalyzed hydroboration of alkynes with an equimolar amount of 1,3,2-benzodioxaborole in tetrahydrofuran efficiently to provide 2-alkenyl-1.3, 2.2-bioxaborol under mild reaction conditions as mentioned in this paper.

TL;DR: The mutual solubilities of 1-ethyl-3-methylimidazolium ethylsulfate, with n-alkanes and aromatic hydrocarbons were measured at ambient pressure by a dynamic method from (250 to 420) K.
Abstract: The mutual solubilities of [EMIM][EtSO4], namely, 1-ethyl-3-methylimidazolium ethylsulfate, with n-alkanes (hexane or octane), aromatic hydrocarbons (benzene, toluene, or ethylbenzene), ketones (pentan-2-one, pentan-3-one, hexan-2-one, or heptan-4-one), ethers (dibutyl ether, tert-butyl-methyl ether, tert-butyl-ethyl ether, or tetrahydrofuran), and with dimethylsulfoxide, DMSO, have been measured at ambient pressure by a dynamic method from (250 to 420) K. The upper critical solution temperatures (UCSTs) were not observed for these systems, because they were at a temperature >420 K. The solubilities of [EMIM][EtSO4] in n-alkanes and aromatic hydrocarbons decrease with an increase of the molecular weight of the solvent. The experimental results have been correlated using the NRTL equation. The average root-mean square deviation of the equilibrium mole fraction for all the liquid−liquid equilibrium (LLE) data was 0.0033.

TL;DR: In this paper, lineshape analysis of 17O spin-echo NMR spectra has been used to study water molecular reorientations in ice-Ih and THF Structure II clathrate hydrate.
Abstract: Lineshape analysis of 17O spin-echo NMR spectra has been used to study water molecular reorientations in ice-Ih and THF Structure II clathrate hydrate. The kinetics was determined by the changes of...
