NaBHT (sodium 2,6-di-tert-butyl-4-methylphenolate), a strong, but hindered and lipophilic base, has been effectively paired with similarly lipophilic, high-reactivity Pd-NHC (N-heterocyclic carbene) catalysts to produce an ideal combination for performing

Pot-economic synthesis of N-aryl acridones was performed with 2-aminobenzophenones and aryl boronic acids as starting materials. Cu-catalyzed chelation-assisted oxidative C–N cross-coupling reactions were well merged with the following intra-molecular oxidative dehydrogenative C–H amination reactions under an air atmosphere. The use of reagent capsules can further resolve the compatibility problem of reagents and simplify the operational process, providing a more straightforward access to the target products.

An efficient copper-catalyzed electrophilic amination strategy has been established for the rapid synthesis of N-aryl-2-aminophenones from readily available arylboronic acids/esters and anthranils. This protocol features good functional group tolerance, broad substrate scope, and operational simplicity. Moreover, a tandem C-H borylation and C-N coupling protocol has also been developed to transform simple arenes to the valuable N-aryl-2-aminophenones in one pot. Additionally, the synthetic potential of this methodology is further demonstrated by the synthesis of various useful N-heterocycles and derivatives.

An efficient and divergent synthesis of N-arylbenzimidazoles and N-arylindazoles from arylamino oximes based on reaction conditions selection was developed. The synthesis was approached by treating oximes with BTC and the chemoselectivity was regulated by the amount of Et3N. This switchable N–N and N–C bond formation process features mild reaction conditions, simple execution, high chemoselectivity and broad substrate scope.

Vinylogy is a widely accepted principle involving the transfer of electronic chemical character through a double bond, and many reactions have been developed by applying this concept. In contrast, phenylogy, which involves the connection of two substituen
