aldehydes, ketones and esters β-carbonyl radicals can be generated via enolization, cyclopropanation, solvomercuration and reduction with NaBH4. Radicals react with electron-poor alkenes to give products of CC-bond formingreactions (Tables 1–3). Carbonyl compounds are therefore precursors of three-carbon building blocks. The products result from reactions with “Umpolung”.
