Three-Component Aminoselenation of Arynes

Area of Science:

• Organic Chemistry
• Synthetic Chemistry

Background:

• Arynes are highly reactive intermediates crucial in organic synthesis.
• Developing efficient methods for C-N and C-Se bond formation is important for accessing novel selenium-containing compounds.

Purpose of the Study:

• To report a novel three-component coupling reaction for synthesizing 2-selanyl aniline derivatives.
• To establish a mild and efficient method for aminoselenation of arynes.

Main Methods:

• Utilized a three-component coupling strategy involving tertiary amines, arynes, and electrophilic selenium sources (aryl selenium bromide or diaryl diselenide).
• Conducted the reaction under mild conditions to promote the formation of C-N and C-Se bonds.

Main Results:

• Successfully synthesized a range of 2-selanyl aniline derivatives.
• Achieved moderate to good yields for the desired products.
• Demonstrated compatibility with various functional groups, indicating broad applicability.

Conclusions:

• The developed three-component coupling reaction provides an effective route to 2-selanyl aniline derivatives.
• The aminoselenation of arynes proceeds efficiently under mild conditions.
• Preliminary mechanistic studies offer insights into the reaction pathway.
