Methanol as a reaction medium and reagent in substrate reactions of rhodium porphyrins.

5 Sep 2009 Methanol solutions of rhodium(III) tetra(p-sulfonatophenyl) porphyrin [(TSPP)Rh(III)] have a hydrogen ion dependent equilibrium between bis-methanol, monomethoxy monomethanol, and bis-methoxy complexes. Reactions of dihydrogen (D(2)) with solutions ... Read more...

Novel and direct transformation of methyl ketones or carbinols to primary amides by employing aqueous ammonia.

Sep 2009 A novel and direct transformation of aryl, heteroaryl, vinyl, or ethynyl methyl ketones or carbinols to corresponding primary amides has been developed. An iodine-NH(3).H(2)O system was proven to be efficient for this reaction and afforded the ... Read more...

Evaluation of selected-ion flow-tube mass spectrometry for the measurement of ethanol, methanol and isopropanol in physiological fluids: effect of osmolality and sample volume.

30 Aug 2009 Selected-ion flow-tube mass spectrometry (SIFT-MS) is particularly suited for the analysis of volatile low molecular weight compounds. We have evaluated this technique for the assay of different alcohols in aqueous solutions, including blood plasma, ... Read more...
