A compound represented by chemical formula 1, a compound represented by chemical formula 2, and a synthetic reagent in a solvent, the synthetic reagent being CsF, KF, 18 - crown -6, K. 2 CO3, [TBAT] The present invention relates to a process for the preparation of diaryl amine compounds comprising a material selected from the group consisting of a (tetrabutylammonium difluorotriphenylsilicate), TBAF (tetrabutylammonium fluoride) and combinations thereof. Chemical Formula 1. Chemical Formula 2. The diaryl amine compound can be synthesized under the absence of a transition metal to be used to synthesize diaryl amine compounds having various substituents.

Transition-Metal-Free Diarylation of Isocyanates with Arynes

A facile method for the transition-metal-free diarylation of isocyanates with arynes in the presence of cesium fluoride has been developed, which affords functionalized diaryl amines in moderate to excellent yields. This reaction has good functional group tolerance and provides excellent regioselectivity by utilizing a methoxy-substituted aryne precursor.
