1,6‐Addition Reactions of Difluoroenol Silyl Ethers with Benzoquinones and Quinonediimines To Access Difluorooxymethyl and Difluoroaminomethyl Compounds

Abstract The etherification and amination of difluoroenol silyl ethers with benzoquinones and quinonediimines were achieved by using hexafluoroisopropanol (HFIP) as the solvent. This 1,6‐addition reaction could construct difluorooxymethyl and difluoroaminomethyl compounds under metal‐free conditions. It is preliminarily speculated that the reaction took place through a single electron transfer (SET) process.
