Insights into chromatographic enantiomeric separation of allenes on cellulose carbamate stationary phase.
Allenes are cumulenes with three contiguous carbons linked together through double bonds. 1,3-disubstituted allenes are not superimposable on their mirror image; as a consequence they are chiral.Expand
