Enone Photochemical Cycloaddition in Organic Synthesis

  • Alan C. Weedon


This chapter is concerned with the light-induced addition of the double bond of α,β-unsaturated ketones to alkenes to give cyclobutanes. The reaction is variously referred to as enone photoannelation, enone (2+2) cycloaddition, the de Mayo-Eaton reaction, or the de Mayo reaction. The last name is, however, usually reserved for the cycloaddition of enolized diketones to alkenes.
