The first three-membered ring substituted spiro-1,2-dioxetane (2) has been synthesized and characterized through the singlet oxygenation of methyleneaziridine 1.Thermodynamic properties of the decomposition of 2 are as follows: K20 deg C = 11.5 s-1; Ea = 18.3 kcal/mol; ΔH(excit.) = 17.9 kcal/mol; ΔS(excit.) = 7.5 eu.The chemical properties of this novel dioxetane are compared to those of dioxetanes 11 and 12, dioxetanimine 9, and dioxetanone 10.

Page/Page column title page; 26-27; 1/2, (2008/12/05)
This invention relates to novel iminium salts, which may be in the form of ionic liquids, and a process for producing electron deficient olefins, such as 2-cyanoacrylates, using such an iminium salt, for instance in the form of an ionic liquid.
