The versatility of DABCO: synthetic applications of its basic ...
2020年4月16日 · Thus, DABCO similarly to Et 3 N can be used as a hydrogen source for the reduction of various organic halides under UV irradiation (Scheme 74). 80 For example, the reduction of 1-bromododec-1-ene was initiated by UV irradiation in the presence of DABCO, leading to dodec-1-ene in 94% yield.
DABCO - Wikipedia
DABCO is a bicyclic organic compound with the formula N2 (C2 H4) 3, also known as triethylenediamine or TEDA. It is a highly nucleophilic tertiary amine base with a pKa of 3.0 or 8.8 in water, and is used as a catalyst, reagent and quencher of singlet oxygen.

2023年9月15日 · The iminyl radical formed under UV irradiation in the presence of DABCO due to single electron transfer (SET) and N–O bond cleavage undergoes selective intramolecular homolytic aromatic substitution (HAS) with formation of a new C–N bond.
Gentamicin Loaded Zn2(bdc)2(dabco) Frameworks as Efficient
2018年1月11日 · The present study was designed to provide Zn 2 (bdc) 2 (dabco) MOF and evaluate its performance in absorbing and releasing gentamicin. Characterization methods, such as FTIR, XRD, SEM, BET, UV–Vis spectroscopy and TGA, were employed to characterize the gentamicin-loaded Zn 2 (bdc) 2 (dabco) structure.
PdCl2/DABCO-catalyzed direct arylation of 2 ... - Springer
2016年5月4日 · Here, we report that PdCl 2 combined with DABCO (1,4-diaza-bicyclo[2,2,2]octane) represents an inexpensive, phosphorus free, air and moisture stable catalytic system to successfully achieve Pd-catalyzed couplings of 2-hydroxybenzaldehydes with aryl halides. Moreover, this methodology is of interest due to the use of water as solvent, thus ...
