Phenolic compounds can be efficiently O-methylated with tetramethylammonium chloride in diglyme or polyethyleneglycol (PEG) at temperatures of 150-160 °C and in the presence of either K2CO3 or NaOH. When applying benzyltrimethylammonium chloride as a reagent, the benzylation and methylation of phenols occurs, with the benzylation product always predominating. With allyl-substituted phenols as s...
The title compound, Ph3(PhCH2)P(+)·Cl(-)·H2O, was obtained unintentionally as the product of an attempted synthesis of a silver di-thio-carbamate complex using benzyl-tri-phenyl-phospho-nium as the counter-ion. The asymmetric unit consists of a phospho-nium cation and a chloride anion, and a water mol-ecule of crystallization. In the crystal, the chloride ion is linked to the water mol-ecule by...
The fully automated combustion ion chromatography (CIC) system presented here combines a highly efficient combustion system with the separation power of ion chromatography (IC). CIC allows for the simultaneous, speciated trace analysis of halide (F, Cl, Br, and I) and sulfur compounds (as sulfate) from subppm to percent levels in any nonaqueous sample matrix. Chloride and sulfur recoveries in t...
Potential new targets for antimalarial chemotherapy include parasite proteases, which are required for several cellular functions during the Plasmodium falciparum life cycle. Four new derivatives of N-alkyl and N-benzyl-1,10-phenanthroline have been synthesized. Those are (1)-N-methyl-1,10-phenanthrolinium sulfate, (1)-N-ethyl-1,10-phenanthrolinium sulfate, (1)-N-benzyl-1,10-phenanthrolinium ch...
Polyvinyl benzyl chloride (PVBC) was synthesized by free radical polymerization of 4-vinylbenzyl using benzoyl peroxide initiator at 60 °C. PVBC synthesised in different solvents such as toluene, xylene, 1,4-dioxane, and tetrahydrofuran. The polymers were structurally characterized 1H NMR FTIR spectroscopic techniques. thermal property the polymer investigated thermogravimetric analysis (TGA) d...
In the present work, compound 3´-(2,6-dimethoxybenzoyl)-benzyl 2,6-dimethoxybenzoate (RM4) was evaluated for its ability as a corrosion inhibitor in 3% chloride medium and using an API 5L X70 steel working electrode. The electrochemical system by techniques such polarization curves (CP) impedance spectroscopy (EIS), finding through values obtained that efficiency of at 50 ppm reached 73.2% agai...
In the title compound, C(17)H(18)NO(2) (+)·Cl(-)·H(2)O, a precursor to novel asymmetric catalysts, the N-containing six-membered ring of the tetra-hydro-quinolinium unit assumes a half-boat conformation. In the crystal, inter-molecular O-H⋯O, O-H⋯Cl, N-H⋯Cl and C-H⋯O hydrogen bonds and C-H⋯π inter-actions link the mol-ecules into a three-dimensional network.
