Single Electron Transfer Reaction

Functionalization of amide bond via the cleavage of a non-carbonyl, C-N σ bond remains under-investigated. In this work, a transition-metal-free single-electron transfer reaction has been developed for the C-N σ bond cleavage of N-acylazetidines using the electride derived from sodium dispersions and 15-crown-5. Of note, less strained cyclic amides and acyclic amides are stable under the reaction conditions, which features the excellent chemoselectivity of the reaction. This method is amenable to a range of unhindered and sterically encumbered azetidinyl amides.

The kinetics of induced electron transfer reaction has been attempted presently with Tetra Methyl Ammonium Chloro Chromate (TMACC) and pentaammine cobalt (III) complexes of α-hydroxy acid in the presence of micelles. The Tetra Methyl Ammonium Chloro Chromate (TMACC) oxidizes cobalt (III) bound and unbound α-hydroxy acids. In Tetra Methyl Ammonium Chloro Chromate (TMACC) induced electron transfer in the complex, the intermediate radical formed dissociates in a nearly synchronous C-C bond cleavage and the rest of it proceeding with C-H fission yielding cobalt (III) complex. With increase in surfactant Sodium Lauryl Ethersulphate (SLES) concentration, an increase in the rate was observed.
