Melamine trisulfonic acid catalyzed regioselective nitration of aromatic compounds under solvent-free conditions
A simple, mild and efficient method for the regioselective nitration of various aromatic compounds usingpoly(4-vinylpyridinium nitrate) (P4VPyN) in the presence of melamine trisulfonic acid (MTSA), is reported.This method provides several advantages such as good selectiveity between ortho and para positions ofaromatic compounds, clean procedure, simple work-up, short reaction times, solvent-fre...
متن کاملConductivity of Thionyl Chloride-Lithium Tetrachloroaluminate Solutions
The specific conductivity of solutions of LiA1C14 dissolved in SOC12 was determined as a function of composition and temperature. An analytical expression from which the conductivity can be calculated is given as a function of the mole fraction of LiA1C14 and temperature in the ranges from 0 ~ to 0.37~ and from -20 ~ to +70~ respectively. LiAIC14-SOC14 mixtures are used commercially as electrol...
متن کاملipso-Nitration of arylboronic acids with bismuth nitrate and perdisulfate.
An efficient and one pot synthetic method of ipso-nitration of arylboronic acids has been developed. The high efficiency, general applicability, and broader substrate scope including heterocycles and functional groups make this method advantageous. Due to its simplicity, we expect to find application of this method in synthesis.
متن کاملC1 Nuclear Quadrupole Interaction in Thionyl Chloride
21 hyperfine multiplets, up to J = 12, have been measured for thionyl chloride (S0C12), by means of microwave spectroscopy in the region 18.0 —26.5 GHz. Nuclear quadrupole coupling constants along the principal axes of inertia were determined to be Xaa ~ ~ 25.004 ± 0.040 MHz, Xbb = 0.009 ± 0.025 MHz and Xce = 25.013 ± 0.031 MHz. Also, coupling constants along the S—CI bond axis (z axis) and two...
متن کاملANTI-BACTERIAL EFFECTS OF BISMUTH COMPOUNDS AND ITS SYNERGY WITH TETRACYCLINE AND METRONIDAZOLE ON HELICOBACTER PYLORl
A bacteriological investigation performed on the biopsies of 1 30 patients with gastrointestinal disorders at the GI section of Imam Khomeini hospital concluded in the isolation of 100 cases of Helicobacler pylori. The antibacterial effects of bismuth salts alone and in synergy with tetracycline and metronidazole were evaluated on the basis of disc diffusion method on 5 randomly selected pu...
