摘要

So far the (EZ) equilibria of the unsaturated nitriles X- CH= CH- CN have been determined for X = CH3 (refsl - S ); C2HS (ref.3); (CH3hCH and (CH3)3C (ref. 6"); C6 HsCH2 (refs2 ,6) and C6HS (refs6 • 7 ) , For other substituents literature only gives two dates of percentage of Z-isomer of NC- CH= CH-CN: 50 at 383 K (ref. 8) and 34 at 453 K (ref.9), Also known is the equilibrium of prototropic isomeriza- tion for X = ClCH2 (ref.10) and that of photoisomerization of 3- ...
