Synthesis of aryl alkyl ethers by alkylation of phenols with quaternary ammonium salts.
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...
متن کاملMicrowave synthesis of quaternary ammonium salts.
The microwave synthesis of several quaternary ammonium salts is described. The synthesis provides comparable or better yields than published methods with reduced reaction times and in the absence of solvent.
متن کاملAntibacterial activity of gemini quaternary ammonium salts.
A series of gemini quaternary ammonium salts (chlorides and bromides), with various hydrocarbon chain and spacer lengths, were tested. These compounds exhibited antibacterial activity against both Gram-positive and Gram-negative bacteria and were not mutagenic. The strongest antibacterial effect was observed for TMPG-10 Cl (against Pseudomonas aeruginosa ATCC 27853) and TMPG-12 Br (against Stap...
متن کاملQuaternary ammonium amalgams as Zintl ion salts and their use in the synthesis of novel quaternary ammonium salts.
dodecapeptide 5 does not seem to follow this trend, which may suggest that secondary interactions exist between the terpenoid and peptide moieties. Although we still need to perform many experiments to develop a reliable mechanistic model to explain the observed phenomenon, our preliminary observations show an interesting potential in this area and investigation along this line is in progress i...
متن کاملInteraction of quaternary ammonium and phosphonium salts with photosynthetic membranes.
Distinct concentration ranges of selected quaternary ammonium and phosphonium salts were elaborated to induce stimulatory or inhibitory effects, respectively, on photosynthetic reactions. By means of fluorescence induction measurements 3 different effects of alkylbenzyldimethylammonium chloride (ABDAC; zephirol) in chloroplast preparations from Pisum sativum were observed. 60 microM ABDAC produ...
