Abstract:
Through the design of a pyridine-activated diyne monomer, the catalyst-free multicomponent polymerizations of sulfur, aromatic alkyne, and a group of commercially available primary and secondary diamines were realized at room temperature or 40 °C, affording functional polythioamides with well-defined structures, high yields (up to 98%), high molecular weights (95 100 g mol-1), improved mercury removal performance, and interesting photophysical and photochemical properties. This work not only demonstrated an advance in efficient and economic synthesis of polythioamides, but also revealed the structure-property relationship of these promising sulfur-containing polymer materials.

Preparation of 1° Amines: Gabriel Synthesis
Strong bases like NaOH or KOH deprotonate the phthalimide to form the corresponding anion, which acts as a nucleophile. Further, the anion attacks an...
Preparation of 1° Amines: Azide Synthesis
Azide ions act as good nucleophiles and react with unhindered alkyl halides to form alkyl azides. Alkyl azides do not participate in further nucleophilic substitution reactions, thereby eliminating the chances of polyalkylated products. Alkyl azides are reduced by hydride-based reducing agents, like lithium aluminum...
Preparation of Amides
The DCC-promoted synthesis of amides begins with the protonation of DCC by carboxylic acid. The protonation makes it a better acceptor. Next, the addition of carboxylate to the protonated carbodiimide gives a reactive acylating agent.
Subsequently, the amine acts as a nucleophile that attacks the acylating agent to form a tetrahedral intermediate. In the...
