Oxygen-Directed Copper-Catalyzed, Diastereoselective Protosilylation of Cyclopropenes

Key Points

• To develop a copper-catalyzed method for the protosilylation of cyclopropenes that shows good selectivity.
• Utilized copper as a catalyst for the reaction.
• Employed oxygen to direct the silylation process.
• Examined various cyclopropene substrates with different functional groups.
• Successfully synthesized organosilanes with cyclopropyl groups.
• Achieved high diastereoselectivity in the reactions.
• Demonstrated the method's broad functional group tolerance.
