Organohypervalent iodine: development, applications, and future directions.
TL;DR: The synthetic utility of organohypervalent iodine reagents will be illustrated by their use in the alpha-Hydroxydimethylacetal formation reaction from enolizable ketones, alpha-hydroxylation,alpha-tosyloxylation and arylation ofketones, carbon-carbon bond formation, and intramolecular cyclopropanation using iodonium ylides.
