2-Diphenylphosphanyl-4-pyridyl(dimethyl) amine as an effective ligand for the ruthenium(II) complex catalyzed homogeneous hydration of nitriles under neutral conditions [PDF]

open access: yes, 2011
New homogeneous catalyst comprised of [Ru(methallyl)(2)(cod)] (cod = 1,5-cyclooctadiene) (1) and 2-diphenylphosphanyl-4-pyridyl(dimethyl) amine (2) is shown to efficiently catalyze the hydration of various nitriles under neutral conditions. The hydration

Coffee with High but Not Low Caffeine Content Augments Fluid and Electrolyte Excretion at Rest

open access: yesFrontiers in Nutrition, 2017
BackgroundLow levels of caffeine ingestion do not induce dehydration at rest, while it is not clear if larger doses do have an acute diuretic effect. The aim of the present investigation was to examine the acute effect of low and high levels of caffeine,
