A tandem thioetherification reaction of 2-(2,2-dibromovinyl)phenol derivatives with
thiophenols and thiols has been developed. In the presence of potassium hydroxide,
2-(2,2-dibromovinyl)phenols reacted with thiophenols and thiols to generate 2-arylthiobenzofurans
and 2-alkylthiobenzofurans in good yields in N,N-dimethylformamide via a one-pot tandem reaction. This method has several advantages
including commercial availability of starting materials, simple operation, and easy
purification of products.
