Abstract

A sunlight-mediated [3 + 2] cycloaddition of azobenzenes with arynes that are in situ generated from ortho-(trimethylsilyl)phenyl triflates has been developed in the absence of transition metals or photocatalysts. This strategy provides an alternative method for the efficient construction of the carbazole backbone.
