Structurally diverse aromatic aldehydes were thioacetalated in a clean and efficient reaction with ethane‐1, 2‐dithiol and thiophenol based on the use of I2 generated in situ from Fe(NO3)3.9H2O/NaI. The reaction occurs in good to high yield in dichloromethane at room temperature and the use of toxic and corrosive molecular iodine is avoided.
在使用Fe(NO 3)3 .9H 2 O / NaI原位生成的I 2的基础上,与乙烷-1、2-二硫醇和苯硫酚进行清洁高效的反应,将结构多样的芳族醛硫缩醛化。在室温下,该反应在二氯甲烷中以高产率高收率发生,避免了使用有毒和腐蚀性的分子碘。
