Abstract

original image

The polymers 2 (R = tBu, Ph; x > 18) have a rigid rodlike structure. These “poly[1.1.1]propellanes” are obtainable by anion-initiated (tBuLi, PhLi) ring-opening polymerization, during which the central CC single bond in the corresponding [1.1.1]propellane 1 is broken. Of particular value in the structural proofs were the CP MAS 13C-NMR spectra.
