摘要

研究了2-炔基双芳基与二硫化物的无金属硫代环化反应。这种温和而高效的方法在廉价的HNO3/HCl的促进下，具有广泛的底物范围和高官能团耐受性，可提供一系列相应的9-亚砜基菲。反应中使用了二硫试剂的两个硫化物基团。

Metal-Free Synthesis of 9-Sulfenylphenanthrenes via HNO3/HCl Promoted Annulation of 2-Alkynyl Biaryls with Disulfides

A metal-free thiolative annulation of 2-alkynylbiaryls with disulfides has been developed. This mild and efficient approach was promoted by inexpensive HNO3/HCl and afforded a range of corresponding 9-sulfenylphenanthrenes in good to excellent yields with a broad substrate scope and high functional group tolerance. Both sulfide groups of the disulfide reagent were used in the reaction.
