Ruthenium-catalyzed hydrative cyclization of 1,5-enynes.
A ruthenium-catalyzed hydrative cyclization of enynes has been developed. The reaction converts a range of 1,5-enynes bearing terminal alkyne and Michael acceptor moieties into cyclopentanone derivatives. From extensive catalyst screening experiments, a trinuclear ruthenium complex, [Ru3(dppm)3Cl5]PF6, has been identified to be an effective catalyst in mediating the 1,1-difunctionalization of a...
متن کاملEffect of chloroacetic acids on the kidneys.
The effects of dichloroacetate (DCA) and trichloroacetate (TCA) administered in drinking water were studied. At high concentrations of either compound, weight loss, or failure to gain weight, was observed. Food consumption was also decreased; both effects were attributed to decreased water consumption. Renal phosphate-dependent glutaminase activity was increased at the highest concentration, an...
متن کاملActivation of a water molecule under mild conditions by ruthenacyclopentatriene: mechanism of hydrative cyclization of diynes.
A ruthenium cyclic biscarbene complex reacted with a H(2)O molecule under mild conditions to produce η(5)-oxapentadienyl complex, that proved to be the intermediate in the catalytic hydrative cyclization of a diyne.
متن کاملRe-evaluation of turbidimetry of proteins by use of aromatic sulfonic acids and chloroacetic acids.
From studies on 11 different proteins (including native albumin and albumin with reduced disulfide-bridges) treated with sulfosalicylic, 2-naphthalenesulfonic, toluenesulfonic, dichloroacetic, or trichloroacetic acids, we elucidate the interactions determining the resulting turbidities and other factors affecting turbidities, and we discuss the clinical utility of such turbidimetry. At least th...
متن کاملDetermination of chloroacetic acids in drinking water using suppressed ion chromatography with solid-phase extraction.
Suppressed ion chromatography with a conductivity detector was developed for the determination of trace amounts of underivatized chloroacetic acids (CAAs). When sodium carbonate and methanol were used as a mobile phase, the simultaneous determination of each CAA took approximately 25 min. The linearity, reproducibility and detection limits were determined for the proposed method. For the solid-...
