Abstract: Hypervalent iodine (III) five-membered heterocycles have found broad application as atom-transfer reagents for organic synthesis. Among them, 1-Phenyl-1,2-benziodoxol-3-(1H)-one is known as a traditional benzyne precursor, but no further synthetic applications have been reported. Herein, we… read more here.

Abstract: Abstract Oxidation of various sugar primary alcohols into corresponding uronic acids was demonstrated using 1-chloro-1,2-benziodoxol-3(1H)-one and TEMPO. The reaction proceeds at room temperature in good to excellent yields. Primary alcohols get oxidized selectively over the… read more here.

DOI: 10.1039/c8nj00530c
Abstract: The application of 1-chloro-1,2-benziodoxol-3-one as a powerful chlorinating agent as well as oxidant for aniline derivatives is explored. The amide directing group assisted radical mediated ortho-selective chlorination proceeds in the absence of a radical initiator.… read more here.
