Electrochemistry of electron transfer probes. Competition between ECE and DISP mechanisms in the reduction of α-aryloxyacetophenones
Research output: Contribution to journal › Journal article › Research › peer-review
The kinetics of the fast unimolecular fragmentation of α-aryloxyacetophenone radical anions in DMF has been analyzed by using a combination of linear sweep voltammetry and independently determined standard potentials or rate constants. The cleavage rates are in the range 3.8 × 105 s-1 to 2.8 × 108 s-1. The mechanism changes from a predominantly DISP mechanism to a predominantly ECE mechanism at fast cleavage rates. It was found that the effect of the heterogeneous electron transfer cannot be neglected when reactions with rate constants above 105 s-1 are studied by linear sweep voltammetry.
