Abstract:
This study reports an efficient and practical synthetic approach for the synthesis of a particularly important class of polymerizable quaternary ammonium salts (PQASs), that is, acryloxyalkyltriethylammonium bromides (AATEABs), which may find application as antimicrobial coatings for commercial membranes with antifouling and anti-biofouling properties, to be used for wastewater treatment. The synthetic method is based on a simple two-step procedure from commercially available substrates, entirely carried out under air and without any need for chromatographic purification. All the newly synthesized AATEABs were tested for their antimicrobial activity, and the results showed that AATEABs bearing an alkyl chain of 11 and particularly 12 carbon atoms possessed significant activity against Gram positive bacteria and yeast strains.

Each alkylation step makes the nitrogen center more nucleophilic, which triggers successive alkylations until a quaternary ammonium salt is formed. Considering...
Preparation of Alkynes: Alkylation Reaction
Alkylation of terminal alkynes with primary alkyl halides in the presence of a strong base like sodium amide is one of the common methods for the synthesis of longer carbon-chain alkynes. For example, treatment of 1-propyne with sodium amide followed by reaction with ethyl bromide yields 2-pentyne.
