Addition of Alcohols Hydrohydroxymethylation , Ethers, and 2-substituted 1,3-Dioxolane s

2 Addition of Alcohols (Hydrohydroxymethylation), Ethers, and (2-substituted) 1,3-Dioxolane(s) 

Although ethers have been used less frequently than alcohols, it has recently been reported that tetrahydrofuran (THF) is photocatalytically activated by TBADT, and the alkylation of unsaturated nitriles is obtained in good yield [15]. As an alternative, the C—Br bond in various glycosyl bromides has been homolytically cleaved, and the resulting radical trapped by acrylonitrile to form the corresponding C-glycosides. The halogen abstraction step is initiated by a photolabile iron-based dimeric metal complex [16].
