p-Nitrophenyl carbonate promoted ring-opening reactions of DBU and DBN affording lactam carbamates
Beilstein Journal of Organic Chemistry, 2016 The amidine bases DBU (1,8-diazabicyclo[5.4.0]undec-7-ene) and DBN (1,5-diazabicyclo[4.3.0]non-5-ene) display nucleophilic behaviour towards highly electrophilic p-nitrophenyl carbonate derivatives with ring opening of the bicyclic ring to form ...

NMR study of ε-caprolactam in various solvents. Graphical determination of monomer shift, dimer shift and dimerization constant from the dilution shift data [PDF]
J. Chem. Soc., Faraday Trans., 1994 A graphical method for the simultaneous determination of the monomer shift, dimer shift and dimerization constant of a self-association system from the dilution NMR shift data is proposed. This method avoids the conventional extrapolation to infinite dilution to obtain the monomer shift. Three self-association systems: Iµ-caprolactam in [2H1]chloroform,

Isolation and Quantification of Polyamide Cyclic Oligomers in Kitchen Utensils and Their Migration into Various Food Simulants. [PDF]
PLoS ONE, 2016 Small amounts of cyclic monomers and oligomers are present in polyamide (PA)-based kitchen utensils. In this study, we isolated eight PA-based cyclic monomers and oligomers from kitchen utensils made from PA6 (a polymer of ε-caprolactam) and PA66 (a ...
