Thiostannylation of arynes with stannyl sulfides: synthesis and reaction of 2-(arylthio)arylstannanesElectronic supplementary information (ESI) available: experimental section. See http://www.rsc.org/suppdata/cc/b4/b405883f/
Arynes were found to insert into a sulfur-tin sigma-bond of stannyl sulfides to give a variety of 2-(arylthio)arylstannanes, whose carbon-tin bonds were applicable to further transformations.

ortho-Quinone methides, arising from a formal [2+2] cycloaddition between arynes and DMF, were found to facilely undergo a [4+2] cycloaddition with ester enolates or ketenimine anions to produce diverse coumarins in a straightforward manner.

accessible by the same protocol using arynes. Based ontheir high reactivity, the tin hydride addition should be arelatively fast process. Surprisingly, to the best of ourknowledge, such a direct synthesis of aryl stannanes viahydrostannation of arynes is not yet been described in theliterature. In general, aryl stannanes are obtained fromaryl halides via halogen–metalexchange (with Mg,

synthetic protocol to realize aromatic perfluoro-tert-butylation. The key to the success is the identification of PFtB phenyl sulfone as a new source of PFtB anion, which reacts with arynes in a highly regioselective manner to afford perfluoro-tert-butylated arenes in high yields. The application of the method is demonstrated by the preparation of sensitive 19F-labeled NMRprobes with an extraordinary resolving

A transition metal-free C−N arylation of easily accessible tertiary anilines enabled by bifunctional arynes is described. The reaction proceeds via a tandem nucleophilic attack of anilines to arynes, followed by a Smiles-Truce rearrangement to furnish synthetically valuable and densely substituted biaryls. This protocol was further utilized for heterocyclic scaffolds, providing access to medium size
