RISA 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...
Indirect synthesis of Bis-2PhIndZrCl2 Metallocene catalyst used for ethylene polymerization
Bis(2-PhInd)ZrCl2 was simply synthesized indirect via the intermediating bis(2-PhInd)ZrMe2 compound from
2-Phenylindene and four equivalents of MeLi. The final product was achieved by use of halogenating agent
(HCl).This method...
Conformation, molecular structure, and vibrational assignment of bis(2,2,6,6-tetramethylheptane-3,5-dionato)copper(II)
Conformational analysis, molecular structure, relative stability, and complete vibrational assignment of bis(2,2,6,6-tetramethylheptane-3,5-dionato)copper(II), Cu(tmhd)2, were investigated by density functional theory (DFT), Natural Bond Orbital...
Ring Opening of Epoxides By Zn(OAc)2 /1,7-Bis(2-Benzoic Acid)-1,4,7-Trioxaheptane (ZnBBATOH) as a New Catalyst
We describe here the highly regioselective Ring Opening of Epoxides with aromatic amines By Zn(OAc)2 /1,7-Bis(2-Benzoic Acid)-1,4,7-Trioxaheptane (ZnBBATOH) as a New Catalyst....
