三、Reaction characteristics：乙烯砜聚乙二醇生物素中乙烯基砜（VS）官能化聚乙二醇（VS-PEG）是一种巯基（-SH）反应性PEG衍生物，可用于通过其可用的巯基修饰生物分子或其他材料。室温下，在pH6.5～8.5的缓冲液中，VS基团容易与游离巯基发生反应。Vinyl sulfone (VS) functionalized polyethylene glycol (VS PEG)...
ARYL-VINYLSULFONE—REAGENTIEN ZUM SCHUTZ UND NACHWEIS VON THIOLFUNKTIONENAryl vinyl sulfones selectively react with thiol groups to acid-stable compounds which easily are cleaved by mild bases to thiol compounds. Ester and amide groups are not attacked under these conditions. Therefore, these ...

The trimethylphosphine-promoted thiol–vinylsulfone Michael addition is found to proceed via the nucleophile-initiated mechanism, in which the attack of trimethylphosphine at divinylsulfone is the rate-limiting step. An amine is superior to an organophosphine for the base-catalyzed mechanism because of...

Our aim was to characterize thiol reactivity of G1 and its conversion products and establish how much of antimicrobial and cytotoxic effects are due to the primary activity of G1 and how much can be attributed to its reaction products. Stability of G1 in growth media as well as its ...
2-(Perfluorodecyl)ethanyl Vinyl Sulfone 2-(Perfluorodecyl)ethanyl 2-chloroethanyl sulfone (3.37 g, 5.00 mmole) and tetrahydrofuran (25 ml) were stirred at 50° and triethylamine (1.01 g, 10.0 mmole) was added, giving an exotherm to 52°. After a half hour at 50°, the reaction mixtu...
