  Generation of Arynes via Ate Complexes of Arylboronic Esters with an ortho-Leaving Group

  摘要：

  An efficient method of generating aryne has been achieved by treating ortho-(trifluoromethanesulfonyloxy)arylboronic acid pinacol ester with tert-or sec-butyllithium. Monitoring the reaction by B-11 NMR has indicated that a boron-ate complex formed in situ is the eventual precursor that converts into aryne near room temperature. The prior formation of the ate complex at a low temperature has enabled us to use various arynophiles, including those bearing base-sensitive groups. The ready availability of the aryne precursors and mutual orthogonality in aryne generation with widely used ortho-silylaryl triflate have enhanced the utility of the method.

  The trimethylsilylmethyl Grignard reagent triggered efficient generation of arynes from various ortho-iodoaryl or ortho-sulfinylaryl triflates. The moderate nucleophilicity and basicity of the reagent facilitated efficient reactions between the aryne precursors and arynophiles containing organometallic nucleophile-sensitive functionalities.
