Synthesis Strategies towards Tagged Homogeneous Catalysts To Improve Their Separation

Area of Science:

• Catalysis
• Green Chemistry
• Organic Synthesis

Background:

• Industrial application of homogeneous catalysts is hindered by challenges in catalyst recycling.
• Existing literature lacks a consolidated overview of synthetic approaches for recyclable homogeneous catalysts.

Purpose of the Study:

• To provide a concise summary of synthesis pathways for modified homogeneous catalysts.
• To examine modular and late-stage synthesis routes for catalyst modification.
• To explore a universal tag library for catalyst recycling strategies.

Main Methods:

• Literature review and synthesis of existing data on catalyst modification.
• Categorization of modification strategies (polar, non-polar, fluorous, molecular-weight-enlarged).
• Analysis of modular and late-stage synthetic approaches.

Main Results:

• Summarized synthesis pathways for various catalyst modifications.
• Evaluated the efficiency of modular and late-stage approaches.
• Identified potential for a standardized tag library.

Conclusions:

• Catalyst modification is key to enabling homogeneous catalyst recycling.
• Modular and late-stage synthesis offer versatile routes for catalyst tuning.
• A universal tag library could streamline catalyst recycling strategies for industrial use.
