Misal, Balu published the artcileSulfated polyborate-H2O assisted tunable activation of N-iodosuccinimide for expeditious mono and diiodination of arenes, Formula: C11H10O, the publication is Tetrahedron Letters (2021), 153154, database is CAplus.
Owing to both Lewis and Bronsted acid active sites on sulfated polyborate under homogeneous conditions, iodination protocol of arenes was developed, which can meet the requirement of regioselectivity and higher yield. The sulfated polyborate activated N-iodosuccinimide for mono iodination of highly activated substrates viz. phenols, anilines under anhydrous condition. Water tuned sulfated polyborate to generate more Bronsted acid sites resulting in rapid activation of NIS for diiodination. The protocol was equally applicable to diiodination of 4-hydroxyphenylacetic acid to synthesize 4-hydroxy-3,5-diiodophenylacetic acid, an intermediate of tiratricol, a thyroid treatment drug. This protocol was further integrated via one-pot sequential iodination and Sonogashira coupling to synthesize aryl acetylenes, building blocks for the synthesis of a variety of specialty chems., API and natural products.
