Substrate-controlled divergent remote C–H and N–H polyfluoroarylation of 2-aminopyrimidines with polyfluoroarenes via Pd(ii)/Pd(0) catalysis
摘要:
Substrate-controlled product divergence is demonstrated in Pd-catalyzed reaction of 2-aminopyrimidines. Remote C5–H polyfluoroarylation occurs with N-alkylpyrimidine-2-amines, while N–H polyfluoroarylation is dominant for N-aryl-pyrimidine-2-amines.

-Aryl-2-aminopyrimidines with Sulfoxonium Ylides to Access 2-Alkyl Indoles Through C-H Bond Activation
A novel synthesis of 2‐alkyl indoles that uses N‐aryl‐2‐aminopyrimidines and sulfoxonium ylides was developed. It is an efficient and mild method for the synthesis of 2‐alkyl indoles. environmentally friendly solvents, efficient alternative carbenoid precursors, and novel catalyst system were used to complete this reaction. Many different directing groups can be used in this process, and the reaction

The first Pd-catalyzedcyclization of N-aryl-2-aminopyridines with 2-iodobenzoic acids for the synthesis of phenanthridinones through C–H bond activation under very low catalyst loadings (down to 0.1 mol% Pd) in water is reported. This protocol features a broad substrate scope and provides easy efficient access to various phenanthridinones.

Ir(III)-catalyzed synthesis of benzimidazoles has been realized under redox-neutral conditions by annulation of aniline derivatives with dioxazolones. The reaction proceeded via a C–H activation–amidation–cyclization pathway with a decent substrate scope.
