An alternative method for generating arynes from ortho-silylaryl triflates: Activation by cesium carbonate in the presence of a crown ether

An alternative method for generating arynes from ortho-silylaryl triflates using cesium carbonate and 18-crown-6 is reported. The method was efficiently applied to a variety of reactions between several arynes and arynophiles. We also demonstrated that the efficiency of aryne generation is significantly affected by the alkali metal countercation of the carbonate.

2, 3, 6, 7 -pentycene tetracarboxylic dianhydride compound and synthesis method thereof

The invention discloses a 2,3,6,7-pentaptycene tetracarboxylic dianhydride compound and a synthetic method thereof. The method comprises three stages. In the first stage, 2,3,6,7-tetramethyl-9,10-p-(2,3-anthryl)anthracene is synthesized; in the second stage, 2,3,6,7-pentaptycene tetracarboxylic acid is synthesized; and in the third stage, 2,3,6,7-pentaptycene tetracarboxylic dianhydride is synthesized. The method is cheap and available in raw materials and high in yield, the purity of products is high, and pentaptycene dianhydride can be efficiently synthesized at low cost. Compared with a series of new polyimide macromolecular materials polymerized from a diamine monomer in the prior art, the compound has great potential application value in the fields of membrane separation materials, dielectric materials and molecular interlocking functional materials.

Aryne cycloaddition reactions of benzodioxasilines as aryne precursors generated by catalytic reductive ortho-C[sbnd]H silylation of phenols with traceless acetal directing groups

Diversely substituted arylsilyl triflates, as aryne precursors for aryne cycloaddition reactions, were accessed from benzodioxasilines. Catalytic reductive C[sbnd]H ortho-silylation of phenols with traceless acetal directing groups was exploited to prepare benzodioxasilines. Sequential addition of MeLi and then trifluoromethanesulfonic anhydride to benzodioxasilines provided arylsilyl triflates in a single pot. Notably, this approach was successfully utilized to prepare sterically hindered 1,2,3-trisubstituted arylsilyl triflates, which ultimately underwent fluoride-mediated aryne cycloaddition.
