- DABCO abstract "DABCO® is a registered trademark of Air Products & Chemicals Inc. for a line of polyurethane manufacturing catalysts and additives that includes 1,4-diazabicyclo[2.2.2]octane and a variety of specialized chemical derivatives and solutions., but "DABCO" is commonly used by chemists as a shorthand acronym for 1,4-diazabicyclo[2.2.2]octane itself. It is a polyurethane catalyst, Baylis-Hillman reaction catalyst, complexing ligand, and Lewis base. It is used to regulate the reaction rate in Flexplay time-limited DVDs by adjusting pH. DABCO and related amines are quenchers of singlet oxygen and effective antioxidants, and can be used to improve the lifetime of dyes. This makes DABCO useful in dye lasers and in mounting samples for fluorescence microscopy (when used with glycerol and PBS). DABCO can also be used to demethylate quaternary ammonium salts by heating in dimethylformamide (DMF).Although the first pKa is 8.8 that is almost the same as ordinary alkylamines, the nucleophilicity is high because the alkyl groups do not disturb the lone pairs.DABCO has been used as a catalyst for a metal-free Sonogashira coupling, with or without microwave enhancement. For example, phenylacetylene couples with electron-deficient iodoarenes to furnish the Sonogashira product in 77% yield with 95% selectivity.Example of a DABCO-catalysed Sonogashira couplingDABCO has also been used for Morita-Baylis-Hilman reaction.The scheme of Baylis Hilman reaction↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑".
