Kombination von Styrol‐ und Dien‐Struktur zu einem zyklischen Dien: Anionische Polymerisation von 1‐Vinylcyclohexen (VCH)

open access: yesAngewandte Chemie, Volume 135, Issue 28, July 10, 2023., 2023
Die lebende anionische Polymerisation von 1‐Vinylcyclohexen (VCH) mit sec‐BuLi als Initiator in Cyclohexan wurde etabliert. Hierbei ist es eine spannende Frage, ob das Monomer als ein 1,3‐Dien oder eher wie ein Styrolderivat reagiert. Die zyklische Struktur des 1,2‐substituierten Monomers führt zu erstaunlichen Effekten auf die Polymerisation, die ...
