Multicomponent polymerization based on Passerini reaction is described. Room temperature of dicarboxyl acid, monoaldehyde, and diisocyanide leads to the formation a new type sequence regulated poly(ester-amide)s in an efficient one-pot process. The was confirmed be stepwise mechanism, resulting polymers were characterized determined linear with backbone repeating unit ester–ester–amide–amide. When functional aldehydes used, side groups could easily introduced at same time, providing simple...
Polyamides with various functional side groups were synthesized via Passerini reaction in a one-pot approach. The polymerization conditions and kinetics as well the resulting polymer structures thoroughly investigated. facile introduction of pendant groups, especially alkynyl alkenyl provides platform for efficient post-polymerization modification by click chemistry.
We report a facile strategy for the synthesis, functionalization, and controlled degradation of high molecular weight polyesters based on itaconic acid (IA) 10-undecenol. A diene monomer, di(10-undecenyl) itaconate (DUI), was synthesized from IA 10-undecenol by esterification reaction. The acyclic metathesis (ADMET) polymerization DUI conducted with Grubbs first-generation catalyst (G-I) to afford (PEIA: P1 P2). Modification three mercaptans (3-mercapto-1,2-propanediol (MP), benzyl mercaptan...

We report a facile method for the synthesis of multi-block copolymers consisting poly(ethylene glycol) (PEG) and poly(ester–amide) segments with an ordered side group sequence via multicomponent polymerization based on Passerini reaction (PR). The technique involves polymer supported liquid-phase three PEG diacid macromonomers (M1–M3) stepwise PR tert-butyl isocyanoacetate functional aldehyde followed by selective hydrolysis, final M1–M3 phenylacetaldehyde 1,6-diisocyanohexane.
We report the first example of realizing multifunctionalization photodegradable polymers for preparation reactive micropatterns. Three o-nitrobenzaldehyde monomers (M1, M2, and M3) with allyl, propargyl, epoxy groups were synthesized in high yields by simple reactions 5-hydroxy-2-nitrobenzaldehyde allyl bromide, propargyl epichlorohydrin, respectively. Passerini multicomponent polymerization (Passerini MCP) M1, or M3 1,6-hexanedioic acid 1,6-diisocyanohexane generated three...
Currently, many fruits are always harvested at the early ripening stage to reduce postharvest losses followed by 1-methylcyclopropene (1-MCP) or ethephon treatment. However, harvesting adversely affects fruit quality, especially for aroma. Methyl jasmonate (MeJA) treatment could induce biosynthesis of bioactive compounds and maintain quality. In present work, contributions MeJA tomato quality during were studied. The results showed that significantly promoted accumulation volatile organic...
Carbon-based materials are frequently employed as anodes for sodium-ion batteries (SIBs) due to their structural stability. This stability enables them withstand the repeated intercalation and de-intercalation of Na + during charge-discharge cycles without significant deformation or performance degradation, thus ensuring long-term operation SIBs. However, high energy density power have been goals Herein, an electrode material combining bismuth (Bi) carbon nanofibres (CNFs) was prepared. Bi...

Halogenated indoles are essential structural motifs in bioactive natural products. Reported herein is an economical and scalable electrochemical protocol for regioselective 3C–H halogenation of indole derivatives. This strategy provides access to a host 3‐iodo‐, 3‐bromo‐, 3‐chloro‐, 3‐thiocyanoindole derivatives under mild conditions using inexpensive (pseudo)halide salts as the sole reagent. The optimized do not require any supplementary electrolyte salts.
An electrochemically induced tandem reaction has been developed for selective N1-alkylation and C3-halogenation of indoles.
