Aryne click chemistry: synthesis of oxadisilole fused benzotriazoles or naphthotriazoles from arynes and azides
摘要:
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. (C) 2010 Elsevier Ltd. All rights reserved.

Arynes formed through fluoride-promoted ortho-elimination of o-(trimethylsilyl)aryl triflates can undergo [3 + 2] cycloaddition with various azides to form substituted benzotriazoles. The rapid reaction times and mild conditions make this an attractive variation of the classical 'click' reaction of azides and alkynes.
