An Efficient Approach to Obtain Trityl Radicals That Are Highly Stable to the Presence of Superoxide

Key Points

• The study aims to develop triarylmethyl radicals with enhanced stability against superoxide by modifying the trityl core.
• Modified the Finland-type trityl core by replacing carboxyl groups with alkoxymethyl substituents.
• Synthesize new trityl radicals and assess their stability in superoxide environments.
• The newly created triarylmethyl radicals displayed extremely high stability when exposed to superoxide.
• This structural modification led to improved resistance compared to traditional trityl radicals.
