styrenes with 1,1,1-trifluoro-2-iodoethane under an oxygen atmosphere in the presence of water give γ-trifluoromethyl alcohols. In this radical reaction, the oxygen atom in the product originates from molecular oxygen, and water is shown to be important to promote the reaction.
在水存在下,在氧气气氛下,苯乙烯与1,1,1-三氟-2-碘乙烷的可见光诱导的光氧化还原双官能化反应,得到γ-三氟甲基醇。在该自由基反应中,产物中的氧原子源自分子氧,水被证明对促进反应很重要。
