Abstract

In the paper the preparation and cis-trans-isomerisations of 1, 2-disubstituted ethenes of the RS-CH= CH-X type, where X= Br, Cl and OC2 H 5 and R= CH3, C2 H 5,(CH3hCH and (CH 3hC are investigated in dependence on temperature and polarity of the medium. In the series of J-chloro-2-alkylthioethenes cis-isomers are more stable, while in the series of 1- ethyloxy--2-alkylthioethenes the trans-isomers are more stable; the equilibrium position is ...
