“…In addition, surface functionalization of inorganic substrate materials can also be accomplished by a one‐step KF reaction. [ 115–117 ] The preparation of functional polymers with AIE properties through KF reaction was first presented by Long et al. [ 118 ] They showed that KF reaction can be used as a clean coupling reaction for fabrication of functional luminescent copolymers with economical, green, and high‐yield.…”

As the core of polymer chemistry, manufacture of functional polymers is one of research hotspots over the past several decades. Various polymers are developed for diverse applications due to their tunable structures and unique properties. However, traditional step‐by‐step preparation strategies inevitably involve some problems, such as separation, purification, and time‐consuming. The multicomponent reactions (MCRs) are emerging as environmentally benign synthetic strategies to construct multifunctional polymers or composites with pendant groups and designed structures because of their features, such as efficient, fast, green, and atom economy. This mini review summarizes the latest advances about fabrication of multifunctional fluorescent polymers or adsorptive polymeric composites through different MCRs, including Kabachnik–Fields reaction, Biginelli reaction, mercaptoacetic acid locking imine reaction, Debus–Radziszewski reaction, and Mannich reaction. The potential applications of these polymeric composites in biomedical and environmental remediation are also highlighted. It is expected that this mini‐review will promote the development preparation and applications of functional polymers through MCRs.

“…For the prompt development of the post-polymerization approach in polymer science, click reactions provide a reliable synthesis platform. Thus, a wide range of click-type reactions have been integrated with polymer synthesis, including thiol–ene, nucleophile–epoxides, 1,3-dipolar cycloaddition of organic azides and terminal alkynes, , multicomponent reactions, − and activated ester–amine reactions . Among the available click-type reactions in polymer synthesis, activated ester–amine chemistry constitutes the most ideal approach not only in polymer chemistry but also in material chemistry due to the easy handling of the reactions involving functional amines.…”

Poly(ethyl 2,2-difluoro-2-(4-vinylphenoxy)acetate) (PSt-OCF2CO2Et) was rationally designed as a vinyl polymer featuring α,α-difluoro-α-(aryloxy)acetate units as activated ester moieties. The aminolysis of PSt-OCF2CO2Et was conducted, resulting in a 100% conversion of ester units to α,α-difluoroacetamide derivatives. This experimental observation showed good agreement with computational analysis at the density functional theory (DFT) level and the DLPNO-CCSD(T) level of theory. Specifically, the aminolysis of α,α-difluoro-α-(aryloxy)acetates was computationally compared with that of structurally similar α,α-difluoroacetates, which are known to show aminolysis reactivity. This revealed that the α-etherification of α,α-difluoroacetates is not detrimental to the aminolysis reactivity despite the presence of an electronegative oxygen atom adjacent to the CF2 units. This research provides a computational understanding of α,α-difluoro-α-(aryloxy)acetates and easy access to new activated ester moieties in polymer chemistry.

“…the reactions included three or more reactants, are attractive as simple methods of preparation of organic compounds with the great molecular diversity. They can be useful as effective synthetic protocols for obtaining the new libraries of compounds with the potential biological activity [10][11][12][13][14][15][16], natural products [10,[14][15][16][17], agrochemicals [10,18], substances for the electronics [19,20], and also unique polymeric materials [21][22][23]. MCRs are characterized by higher atom economy and require less efforts comparing with the laborious stepby-step procedures of organic synthesis.…”

The gel type microscopic polymer beads bearing epoxy functionalities were modified using the two-stage procedures in order to decorate their surface with the moieties of the zeroth order PAMAM type dendrimer and different heterocyclic aldehydes (2-pyridinecarboxaldehyde, 2-pyrrolidinecarboxaldehyde, furfural or 2-thiophenecarboxaldehyde). The polymeric supports provided in this manner were then used for the immobilization of copper(II) ions. The resulting materials were characterized using different instrumental techniques (optical microscopy, SEM, FTIR microscopy, DR UV–Vis, ICP-OES, and thermal analysis). They were also used as catalysts in the model A3 coupling reaction of benzaldehyde, morpholine and phenylacetylene. The best catalytic activity was found for the polymeric catalyst bearing 2-pyridinecarboxaldehyde moieties. It turned out to be effective in the A3 coupling reactions included different benzaldehyde, alkyne, and secondary amine derivatives, as well. It could also be recycled several times without a significant decrease in its activity in the model A3 coupling reaction. Graphic Abstract
