ELECTRON TRANSFER REACTIONS OF ALIPHATIC ESTERS TO THE CORRESPONDING ALIPHATIC KETONES BY LITHIUM 4,4'-DI-T-BUTYLBIPHENYL RADICAL ANION

Sonication of some representative aliphatic esters with lithium in the presence of catalytic amounts of 4,4'-di-t-butylbiphenyl (DBB) in dry THF under N2 afforded the corresponding aliphatic ketones in good yields.Monitoring studies by GC/MS and 1H-NMR spectroscopy after quenching indicate the intermediacy of the corresponding β-ketoesters.
