文摘

A conceptually new strategy has been described for the mild, practical, and environmentally friendly preparation of naphthols and furans using a visible-light promoted photoredox neutral approach. These reactions between accessible electron-deficient bromides and commercially available alkynes could be carried out at room temperature in good-to-excellent chemical yields without any external stoichiometric oxidants.
