WebOct 4, 2024 · Maleimide Thiol Reaction Mechanism – Michael Addition. The maleimide thiol reaction mechanism involves a Michael addition reaction where the maleimide acts as the Michael acceptor while the thiolate is the Michael donor. Depending on how strong a base the nucleophile is, it will undergo either direct addition or conjugate addition. The ... WebSep 21, 2024 · Computational studies have delivered valuable mechanistic insights into thiol Michael additions, which are important C S bond-forming reactions used in biological and …

Thiol-ene additions are known to proceed through two mechanisms: free-radical additions and catalyzed Michael additions. Free-radical additions can be initiated by light, heat or radical initiators, which form a thiyl radical species. The radical then propagates with an ene functional group via an anti-Markovnikov addition to form a carbon-centered radical. A chain-transfer step removes a hydrogen radical from a thiol, which can subsequently participate in multiple propaga… WebFeb 2, 2024 · The key attribute of the thiol-Michael addition reaction that makes it a prized tool in materials science is its modular “click” nature, which allows for the implementation … WebDec 1, 2024 · Scheme 1.
