Abstract

Electroreduction of Organic Compounds, 13. – Coelectroreduction of Methyl Dithiocarboxylates with Halogenoarenes Coelectroreduction of methyl dithiopivalate (1) or dithiobenzoate (11) with a monohalogenobenzene does not result in any characteristic products. However, the aryl methyl dithioacetals 7 and 8 are formed on cathodic reduction of 1 in the presence of the o-dihalogenobenzenes 4 and 5, respectively. – An SNAr mechanism is proposed, which is also in accordance with the formation of 2-bromobenzenethiolate (9) from 1 and 4 or 5.
