一般說明
Acylation, a replacement to silylation, allows the conversion of compounds that consist of active hydrogens (-OH, -SH and -NH) into esters, thioesters, and amides via the action of a carboxylic acid or derivative. The carbonyl group adjacent to the halogenated carbons is known to improve the electron capture detector (ECD) response. Acylation has several advantages:
2,2,6,6-Tetramethyl-3,5-heptanedione is a reagent used to form fragmentation-directing derivatives for GC/MS analysis.
- It enhances the stability of compounds by protecting unstable groups.
- It may confer volatility on substances like carbohydrates or amino acids, that have several polar groups that they are non-volatile and usually decompose on heating.
- It facilitates the separations not possible with underivatized compounds.
- Compounds are detectable at very low levels with an ECD.

[reaction: see text]. In the copper salt catalyzed ether formation from aryl bromides or iodides and phenols, 2,2,6,6-tetramethylheptane-3,5-dione (TMHD) was found to greatly accelerate the ordinarily difficult reaction, making it occur under more moderate temperatures and reaction times. A series

The potential of the stable isotope 26Mg (natural abundance 11.01 atom %) as a biological tracer has been explored using neutron activation (NA) and mass spectrometry (MS) for detection. The high natural abundance of this isotope restricts its utility to

Laser photoionization and ligand photodissociation in Ln(thd)(3) (Ln = Eu, Tb, Gd; thd = 2,2,6,6-tetramethyl-3,5-heptanedionato) are studied in a molecular beam via time-of-flight mass spectrometry. The fragmentation patterns are strongly wavelength dependent. With 355 nm excitation, the mass spectrum is
