A novel noninstrumented technology (ChemTrak AccuMeter) for the quantitative measurement of analytes in biological fluids was reported at the 1990 Oak Ridge Conference (Clin Chem 1990;36:1591-7). This instrument-free technology has been adapted for t

The synthesis and spectral characteristics of a bis-spiro compound: 2,6-bis(4-phenyl-3-δ1-pyrazolinyl)cyclo-hexanone are reported. Unlike literature reports, this particular δ1-pyrazoline does not readily rearrange to the 2 isomer on heating. Pyrol

Evaluation of HPLC as a possible method by which the nitrogen compounds in coal-derived liquids could be analyzed has met with mixed results. Some chromatography fractions display very different HPLC traces in methanol compared with those obtained in

A number of 1-alkyl-4-methyl-2-pyrrolidones have been prepared from methyl 4-alkylamino-3-methyl butenoates. The corresponding 1-alkyl-3-methyl-pyrrolidines are obtainable by the reduction of the pyrrolidones with lithium aluminum hydride. The mass s

The synthesis and spectral characteristics of certain bis(1-alkyl-3-phenyl-2-aziridinyl)ketones are reported. The reactions of 1,2,4,5-tetrabromo-1,5-diphenyl-3-pentanone (2) with primary amines are assumed to have a mechanism similar to that of a si
