Diarylation of N- and O-nucleophiles through a metal-free cascade reaction

The arylation of heteroatom nucleophiles is a central strategy to reach diarylated compounds that are key building blocks in agrochemicals, materials, and pharmaceuticals. Nucleophilic aromatic substitution is a classical tool for such arylations, and recent developments in hypervalent iodine-mediated arylations allow a wider scope of products. Herein, we combine the benefits of these strategies to enable an efficient and transition-metal-free difunctionalization of N- and O-nucleophiles with two structurally different aryl groups and to provide di- and triarylamines and diaryl ethers in one single step (>100 examples). The core of this strategy is the unique reactivity discovered with specifically designed fluorinated diaryliodonium salts, which unveils novel reaction pathways in hypervalent iodine chemistry. The methodology is suitable for diarylation of aliphatic amines, anilines, ammonia, and even water. It tolerates a wide variety of functional and protecting groups, with the retained iodine substituent easily accessible for derivatization of the products.

Palladium Acetate-Mediated Cyclizations of Di- and Trifunctional Triarylamines, Diaryl Ethers, and Diaryl Ketones

Triphenylamine and its 4,(4',4")-substituted nitro or ester and methyl derivatives are cyclodehydrogenated to the corresponding carbazole derivatives 4a-d with Pd(OAc)2 in acetic acid.Further cyclizations can not be observed.Multiple cyclizations of this kind, however, can be realized with compounds of the 1,4-diphenoxybenzene (6a), 1,4-dibenzoylbenzene (6b), and 2,8-diphenoxydibenzofuran type (10), where in a very simple manner benzobisbenzofurans 8a, 9a, indenofluorene-6,12-dione (8b), 11H-fluorenobenzofuran-11-one (8c), and bisbenzofurodibenzofuran (12) become accessible.
