Abstract: Abstract Chemical degradation of poly (bisphenol A carbonate) is achieved using an easy-to-use organocatalyst, TBD (1,5,7-triazabicyclo [4.4.0]-dec-5-ene). Because of increased concern over bisphenol A (BPA) acting as a potent hormone disruptor, proper disposal of end-of-life… read more here.

Abstract: The questionable mechanism initially proposed to explain how 1,5,7-triazabicyclo[4.4.0]dec-5-ene (TBD) allows us to ring-open β-lactones, such as β-butyrolactone (BL), is reinvestigated here. With the use of a trisubstituted β-lactone, i.e. (R,S)-benzylcarbonyl-3,3-dimethyl-2-oxetanone, and the association of… read more here.
