Direct synthesis of ortho-dihalogenated arylpyrimidines using calcium halides as halogen sources
Pyrimidines and their derivatives have been used as important motifs in materials and medicinal chemistry. In this Letter, a wide variety of ortho-dihalogenated arylpyrimidines were synthesized with high yields and functional-group tolerance using calcium

Palladium-catalyzed monoselective halogenation of C-H bonds: Efficient access to halogenated arylpyrimidines using calcium halides
A wide variety of ortho-halogenated arylpyrimidines were prepared with high monoselectivity and functional-group tolerance by using calcium halides as crucial halogenating agents and cupric trifluoroacetate as oxidant in the presence of air.
