RISNovel bis-pyrimidine derivatives: Synthesis and characterization
In summary, new bis-pyrimidine derivatives (4a-g) were prepared in a three-step procedure based on 5-bromo-2,4-dichloro-6-methylpyrimidine (1) as starting material. In spite of our expectation based on our previous studies, the heterocyclization...
A Mild, simple and efficient method for selective α-monobromination of 1,3diketones and β-keto-esters using bis(2-N-methylimidazoliummethyl)ether dichloride
-bromination of dicarbonyl compounds using bis(2-N-methylimidazoliummethyl)ether dibromochlorate. This novel ionic liquid brominated β-dicarbonyl compounds to give a high to excellent yields of the corresponding monobrominated compounds.
Conclusion: We have developed...
Novel bis-pyrimidine derivatives: Synthesis and characterization
Introduction: Pyrimidine nucleus has played crucial role in the history of heterocyclic chemistry and has been used extensively as important pharmacophor and synthon in the field of organic chemistry and drug design. Bis-heterocyclic compounds...
Synthesis and electroluminescent properties of a novel electroluminescence material of bis 2 (4 (diphenylphosphino)phenyl)benzo[d]oxazole (DPB)

Structure and vibrational assignment of bis(benzoylacetone)copper(II)
-diketonates of various metals have been used in the preparation of supported catalysts and as precursors of heterogeneous catalysts
[1,2]. In this paper we synthesized bis(benzoylacetonato)copper(II), Cu(BA)2, by mixing copper(II) acetate...
Ionic liquids as highly efficient and reusable catalyst for one-pot synthesis of bis-α-aminophosphonate
Ionic liquids (ILs) have gained great attention in recent years [1]. ILs have a high polarity and low vapor pressure. These characteristics combined with immiscibility with most of the less polar organic solvents led to ...
