Aryne click chemistry: synthesis of oxadisilole fused benzotriazoles or naphthotriazoles from arynes and azides

The oxadisilole fused benzotriazoles or naphthotriazole derivatives have been synthesized by 1,3-dipolar cycloaddition of various azides with arynes generated in situ from benzobisoxadisilole or 2,3-naphthoxadisilole in good yields under mild conditions.
