Herein
we report the design and synthesis of hypervalent trifluoromethylthio-iodine(III)
reagent 1 and the elucidation of its structure by NMR
spectroscopy and X-ray crystallography. The trifluoromethylthiolation
reactions of 1 with various nucleophiles were explored,
and this compound was found to be a versatile electrophilic reagent
for the transfer of a trifluoromethylthio group (−SCF3). The hydrogen-bonding mode responsible for the activation of 1 by the solvent 1,1,1,3,3,3-hexafluoro-2-propanol was investigated
both experimentally and computationally.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
