Summary
Researchers developed a minimalist method for oxygen-tolerant reversible addition-fragmentation chain transfer (RAFT) polymerization. This approach utilizes trithiocarbonate radicals for initiation, enabling polymerization even in the presence of oxygen.
Area of Science:
- Polymer Chemistry
- Radical Polymerization
- Materials Science
Background:
- Fully oxygen-tolerant reversible deactivation radical polymerization (RDRP) is a significant area of research.
- Existing methods often require complex procedures or specific conditions.
Purpose of the Study:
- To introduce a new, minimalist method for fully oxygen-tolerant reversible addition-fragmentation chain transfer (RAFT) polymerization.
- To investigate the role of trithiocarbonate (TTC) radicals in initiating polymerization and tolerating oxygen.
Main Methods:
- Utilized bis(trithiocarbonate) disulfides (BisTTC) as an iniferter agent.
- Employed high-throughput screening to identify key initiating species.
- Analyzed polymerization kinetics to confirm 'living' polymerization characteristics.
Main Results:
- Successfully achieved fully oxygen-tolerant RAFT polymerization using a minimalist approach.
- Demonstrated that sulfur-centered trithiocarbonate (TTC) radicals initiate monomer polymerization.
- Identified dodecyl-substituted TTC as crucial for oxygen tolerance via radical initiation and deoxygenation.
Conclusions:
- The trithiocarbonate radical initiation strategy offers a powerful and minimalist tool for oxygen-tolerant RDRPs.
- This method simplifies the process of conducting RAFT polymerization under ambient, oxygen-rich conditions.

00:57Cationic Chain-Growth Polymerization: Mechanism
2.3K
The cationic polymerization mechanism consists of three steps: initiation, propagation, and termination. In the initiation step of the polymerization process, the π bond of a monomer gets protonated by the Lewis acid catalyst, which is formed from boron trifluoride and water. The protonation of the π bond generates a carbocation stabilized by the electron‐donating group. In the propagation step, the π bond of the second monomer acts as a nucleophile and attacks the...

01:26Radical Substitution: Hydrogenolysis of Alkyl Halides with Tributyltin Hydride
1.8K
Radical substitution reactions can be used to remove functional groups from molecules. The hydrogenolysis of alkyl halides is one such reaction, where the weak Sn–H bond in tributyltin hydride reacts with alkyl halides to form alkanes. Here, the reagent Bu3SnH yields tributyltin halide as a byproduct.
The bonds formed in this reaction are stronger than the bonds broken, making it energetically favorable. The reaction follows a radical chain mechanism similar to radical halogenation...

01:10Radical Chain-Growth Polymerization: Overview
2.4K
Chain-growth or addition polymerization is successive addition reactions of monomers with a polymer chain. In radical chain-growth polymerization, the reaction proceeds via a free-radical intermediate. The free radical is formed from radical initiators, which spontaneously generate free radicals by homolytic fission. Organic peroxides (such as dibenzoyl peroxide, as shown in Figure 1) or azo compounds are popular radical initiators. A low concentration ratio of radical initiator to monomer is...

01:09Radical Chain-Growth Polymerization: Mechanism
2.5K
The radical chain-growth polymerization mechanism consists of three steps: initiation, propagation, and termination of polymerization. The polymerization initiates when a free radical generated from the radical initiator adds to the unsaturated bond in the monomer. The unpaired electron of the free radical and one π electron in the unsaturated bond creates a σ bond between the free radical and the monomer. As a result, the other π electron in the unsaturated bond converts this...

01:16Radical Reactivity: Nucleophilic Radicals
2.1K
Radicals adjacent to electron-donating groups are called nucleophilic radicals. These radicals readily react with electrophilic alkenes. The SOMO–LUMO interactions are the driving force for the reaction, where the high-energy SOMO of the electron-rich, nucleophilic radicals interacts with the low-energy LUMO of the electron-deficient, electrophilic alkenes. Such SOMO–LUMO interactions are the basis of reactive radical traps, affecting the selectivity in radical reactions. For...

01:20Radical Reactivity: Concentration Effects
1.5K
In a radical reaction, the concentration of starting materials governs the selectivity of a radical. For example, the reaction between an alkyl halide and an alkene, in the presence of tin hydride and AIBN, begins with the generation of a tin radical. The generated radical then abstracts halogen from the alkyl halide, producing an alkyl radical. This alkyl radical can either react with tin hydride, yielding an alkane, or add to an alkene, generating a nitrile-stabilized radical, eventually...
