Abstract
An effective deoxygenative C(sp3)-C(sp3) bond formation reaction is achieved through electrochemical reduction of alcoholic phosphates or sulfonates with aldehydes or ketones. Alcohol derivatives of phosphates undergo single-electron reduction under electrochemical conditions followed by a spontaneous cleavage of the C-O bond with the exothermic loss of phosphate resulting in an alkyl radical species. Subsequently, radical intermediates are further reduced to carbanions at the cathode, which are in situ trapped by carbonyl compounds, thus accomplishing a deoxygenative Barbier-type reaction.

Abstract
Despite the low bond strength of the oxygen-oxygen bond, organic peroxides are often surprisingly resistant to cleavage by nucleophiles and reductants. As a result, achieving decomposition under mild conditions can be challenging. Herein, we explore the reactivity of a selection of peroxides toward thiolates, phenyl selenide, Fe(II) salts, and iron thiolates. Peroxides activated by conjugation, strain, or stereoelectronics are rapidly cleaved at room temperature by thiolate anions, phenylselenide, or Fe(II) salts. Under the same conditions, unhindered dialkyl peroxides are only marginally reactive; hindered peroxides, including triacetone triperoxide and diacetone diperoxide (DADP), are inert. In contrast, all but the most hindered of peroxides are rapidly (<1 min at concentrations down to ∼40 mM) cleaved by mixtures of thiols and iron salts. Our observations suggest the possible intermediacy of strongly reducing complexes that are readily regenerated in the presence of stoichiometric thiolate or hydride. In the case of DADP, an easily prepared explosive of significant societal concern, catalytic amounts of iron and thiol are capable of promoting rapid and complete disproportionation. The availability of inexpensive and readily available catalysts for the mild reductive degradation of all but the most hindered of peroxides could have significant applications for controlled remediation of explosives or unwanted radical initiators.
