Abstract
Samples of dimer and trimer derived from chiral propylene oxide, having head‐to‐tail linkages were prepared using an aluminium complex of a Schiff's base and were studied by means of 13C NMR spectroscopy. Based on these spectroscopic data and on J‐Modulated Spin Echo Technique (JMSET), analysis of a racemic oligomer (DPn ≈ 11) was carried out. Resonances of carbon atoms of central and terminal units were identified. End‐group carbon atoms (with the exception of CH2Cl) present large configurational effects as compared to internal carbon atoms.This publication has 14 references indexed in Scilit:
