Synthesis, Spectral Studies and C-S Bond Fission of Some Alkyl- Diacetates

Some methyl and ethyl diacetates have been synthesized and their structures were identified. A correlation was found between δ-values of benzylidene protons and ?-Hammett values. The internal chemical shift of the methylene proton was found to be structural and applied field dependent. The carbon-sulfur bond fission by the action of sodium hydroxide solution in 50 percent aqueous-dioxane medium, in addition to the alkaline ester hydrolysis was studied. 2- or 4-Nitro compounds gave dicarboxyazoxybenzenes. This led to the suggestion that the reaction might proceed through two intermediates namely diacetic acid and nitrosobenzoic acid. However, the C-S bond fission of other compounds gave aldehydes, supporting that, no α-proton abstraction took place for these compounds.
