Overview

Randomized trial identifies protonation as crucial to enhance cycloaddition efficacy in CO2 conversion, indicating significant advancements for sustainability.

Key Points

This work aims to evaluate the effects of protonation on phosphonium catalysts in the cycloaddition of CO2 to epoxides.
Synthesis of triphenylphosphonium salts and protonated catalysts.
Evaluation of catalysts under mild conditions (0.1 MPa, 80-120 °C) for CO2 cycloaddition to epoxides.
Mechanistic analysis using in situ FT-IR and factorial design of experiments.
Protonated catalyst 3 achieved a yield of 96% for styrene oxide conversion within 6 hours at 2 mol% loading.
Temperature had the most significant impact on yields, optimizing at 120 °C with 96-98% conversion rates detectable for various epoxide structures.
Demonstrated high tolerance for diverse functional groups without the need for high pressures or additives.
