Description

General description

1,4-Diazabicyclo[2.2.2]octane (DABCO, triethylenediamine), a caged tertiary diamine, is commonly used as an organic base in chemical synthesis. It can also be employed as a complexing ligand and as a catalyst. Its gas-phase electronic absorption spectrum, vibrational spectra, multiphoton ionization (MPI) and two-photon fluorescence excitation (TPFE) spectra have been recorded and analyzed. Protonmagnetic resonance (PMR) studies of DABCO in solid state were conducted in order to determine its linewidth, second moment and spin-lattice relaxation time.

Application

1,4-Diazabicyclo[2.2.2]octane (DABCO) may be used in the synthesis of isoxazole derivatives via dehydration of primary nitro compounds in the presence of dipolarophiles. DABCO may be used in the preparation of the following:
• DABCO bis(perhydrate)
• DABCO monohydrate
• DABCO hexahydrate
