Proton-coupled electron transfer ring opening of cycloalkanols followed by a Giese radical addition enabled by an electron donor−acceptor complex

Herein, we describe the formation of an electron donor−acceptor (EDA) complex between electron-richcycloalkanols and electron-deficient alkenes that triggers the proton-coupled electron transfer ring opening of strained andunstrained cycloalkanols without the need for an external photocatalyst. This...

Sumario:Herein, we describe the formation of an electron donor−acceptor (EDA) complex between electron-richcycloalkanols and electron-deficient alkenes that triggers the proton-coupled electron transfer ring opening of strained andunstrained cycloalkanols without the need for an external photocatalyst. This activation generates a remote alkyl radical thatundergoes a Giese reaction with the Michael acceptor in an efficient manner. Mechanistic investigations corroborate both theformation of the EDA complex and the consecutive Giese reaction
