Abstract

Chemical equilibration studies of isomeric alkyl-substituted divinyl ethers have been carried out. The thermodynamic data obtained are used for discussions concerning the spatial structure of the C= C-0-C= C system in these compounds. Divinyl ethers unsubstituted in the a position probably exist mainly in the planar (or nearly planar) s-trans, s-trans form, the planar s-cis, s-trans form being in any case excluded as the most stable structure. The ...
