A new benzoylation procedure was developed which was more reliable than the most common benzoylation procedures in terms of reaction time, peak resolution, detector response and repeatability. Methylamine, putrescine, cadaverine, tryptamine, beta-phenylethylamine, spermidine, spermine, histamine, tyramine and agmatine were studied.

A high-performance liquid chromatography coupled with Q-time of flight mass spectrometry (HPLC/Q-TOF MS) method was developed and validated for the determination of 1, 3-diaminopropane, putrescine, cadaverine, spermidine and spermine in human plasma. The plasma samples were first pretreated by 10%

Conditions are reported for the facile, high-yielding coupling of acyl chlorides with terminal alkynes in a reaction involving palladium and copper iodide; the reaction is tolerant of a wide variety of acyl chlorides and terminal alkynes and provides a convenient

The benzoxyl radical is a key intermediate in the combustion of toluene and other aromatic hydrocarbons, yet relatively little experimental work has been performed on this species. Here, a combination of electrospray ionization (ESI), multistage mass spectrometry experiments, and density
The direct sulfenylation and sulfonylation of (sp(2))C-H bonds of benzamide derivatives were achieved using a Ni catalyst with the aid of an 8-aminoquinoline moiety as a bidentate directing group. These protocols represent a convenient route for the formation of valuable
