Highly Efficient Reduction of Unactivated Aryl and Alkyl Iodides by a Ground-State Neutral Organic Electron Donor

摘要

Reactive intermediates,namely radicals and organometallic species,can be formed by reduction of an organic substrate with an electron donor.Metals in low oxidation states frequently perform this role,and indeed,most electron-transfer reduction processes feature this route.Alternative methods include electrochemical reduction at a (usually metal) cathode,reduction by solvated electrons,reduction by lithium naphthalenide or related radical anions of organic molecules,or photochemically assisted electron transfer.
