Abstract:
Here we reported a versatile and multicomponent polymerization (MCP) approach that enabled the synthesis of functional poly(propargyl imine)s with well-defined structures and high molecular weight (Mw up to 38 200) in excellent yields (up to 93%) from readily accessible monomers of dibromoarenes, isonitriles, and diynes. This MCP had the advantages of simple operation, wide substrate scope, and mild reaction conditions. The resulting polymers possessed good solubility and showed high thermal stability and refractive indices. The tetraphenylethene-containing polymer displayed a phenomenon of aggregation-induced emission and could respond to various acidic vapors.

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.
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...
