A full 1H and 1C NMR study through the use of one-and two-dimensional techniques (HMQC, HMBC, TOCSY and NOE-di †erence spectroscopy) was carried out on poly[3-(6-methoxyhexyl)-2,2@-bithiophene]. Inter-ring correlations detected in the HMBC spectra proved to be a valuable tool in the assignment of re

Synopsis
Poly(l,5-hexadiene) was prepared and its structure characterized by high-field I3C nuclear magnetic resonance. The polymer was shown to contain repeating five-membered rings separated by methylene bridges, with both cis and truns placements present in a 54 : 46 ratio. The result is compatible with the Marvel-Garrison two-step reaction mechanism.
