Radical mediated thiol-yne polymerization reactions complement the more well-known thiol-ene radical polymerization processes, with the added advantage of increased functionality. In one system studied, the rate constant for the addition of the thiol to the vinyl sulfide created by the initial reaction...
The catalyst recyclability and the extension of the methodology for thiol–yne click chemistry are additional benefits. A competitive study among thiophenol, styrene, and phenyl acetylene revealed that the rate of reaction is in the order of thiol–yne>thiol–ene>dimerization of thiol in [hmim]Br...
Subsequent thiol–ene or thiol–yne reaction with thioglycolic acid or 2-mercaptosuccinic acid leads to polymers with carboxylate functionalities, which were conjugated with cisplatin (cis-diamminedichloroplatinum(II) (CDDP)) to generate a drug carrier for Pt-drugs. Only the polymers modified with 2...

Thiol-ene click chemistry. 来自 万方 喜欢 0 阅读量: 904 作者: Charles?E. Hoyle,Christopher?N. Bowman 摘要: Following Sharpless visionary characterization of several idealized reactions as click reactions, the materials science and synthetic chemistry communities have pursued numerous routes toward the ...
Thiol-ene click chemistry proceeds under mild conditions either neat or in benign solvents under UV light to install functionality on vinyl groups [21,22]. This reaction was used to functionalize polybutadiene by Coughlin et al., and was applied to upcycling of poly(acrylonitrile butadiene styrene...
Click chemistryFunctionalizationThiol-eneThiol-ene click chemistry was used for the preparation of polystyrene grafted multiwall carbon nanotubes (MWCNTs) via the thermal initiation method. The thiol end-functional PSt (PSt-SH) was prepared by the nucleophilic substitution reaction of the bromide end ...
For the first time thiol-ene click chemistry was used for the immobilization of Ru(bpy) 3 2+. The immobilization method is simple, fast, and efficient. The ECL sensor exhibited excellent stability in organic solvent and good reproducibility.关键词: Electrochemiluminescence sensor Ru(bpy) 3 2 C...
thiol–ene click chemistryFunctionalized pyrrolidinium compounds, 3-((2-hydroxyethylthio)methyl)-1,1,4-trimethylpyrrolidinium and 3-((2-carboxyethylthio)methyl)-1,1,4-trimethylpyrrolidinium chlorides, are prepared from N,N-diallyl-N,N-dimethylammonium chloride by radical thiol-ene addition and are ...
The influence of alkene functionality on the energetics and kinetics of radical initiated thiol-ene click chemistry has been studied computationally at the CBS-QB3 level. Relative energetics (ΔH°, ΔH(++), ΔG°, ΔG(++)) have been determined for all stationary points along the step-growth...
