Diazomethyl-λ3-iodane meets aryne: Dipolar cycloaddition and C-to-N iodane shift leading to indazolyl-λ3-iodanes Diazomethyl-λ3-iodanes have recently emerged as carbyne equivalents in organic synthesis, enabling the construction of multi-substituted carbon centers through strategic sequential activation of the diazo and iodane functional groups. Distinct from such reaction modes, we report here on the reactivity of diazomethyl-λ3-iodanes as iodane-bound 1,3-dipoles toward arynes.

Easy access to polyhalogenated biaryls: regioselective (di)halogenation of hypervalent bromines and chlorines† Polyhalogenated biaryls are unique motifs offering untapped potential as versatile building blocks for the expedient synthesis of complex biaryl compounds.
