Reaction of lithium metal with benzil in THF. A kinetic study

The kinetics of benzil reduction by lithium metal in THF were investigated under different reaction conditions. The main reaction products were phenylacetophenone and bibenzyl; 1,2-diphenylethanol and diphenylethene were minor products. The first radical anion intermediate formed by electron transfe...
