摘要

Push-pull ethylenes have been prepared, which in the ground state are twisted around the double bond, and the barriers for passage through a planar transition state have been measured with DNMR. The influence of steric and electronic factors on the rotational barriers has been investigated. Compounds have also been prepared where two barriers could be measured, one for passage through the planar state, and the other for passage through a ...
