Nucleophilic addition of sulfoxonium ylides to hypervalent iodine diazo compounds as N-terminal electrophiles: direct access to novel functionalized hydrazones

The nucleophilic addition of sulfoxonium ylides to hypervalent Iodine diazo reagents as N-terminal electrophiles leads to highly functionalized hydrazones. The operational simplicity, wide scope, high product yields and mild conditions are notable features of the methodology.
