The formation of carbon–carbon (C–C) bonds is fundamental to the construction of complex organic molecules in pharmaceuticals, agrochemicals, and materials science. However, many traditional C–C bond-forming reactions rely on expensive, toxic metal catalysts and generate significant chemical waste. In light of growing environmental concerns and the principles of green chemistry, this study focuses on the design and development of environmentally benign catalysts for sustainable C–C bond formation.

We report the synthesis of a novel class of heterogeneous organocatalysts derived from naturally abundant lignin and modified with proline-based functional groups. These green catalysts were tested in key reactions such as the Aldol, Michael, and Knoevenagel condensations under solvent-free conditions. Spectroscopic (FTIR, NMR) and microscopic (SEM, TEM) analyses confirmed successful functionalization and catalyst morphology. The catalytic efficiency was evaluated through reaction yield, turnover number, and recyclability over multiple cycles.

Our findings demonstrate that the bio-derived catalysts not only offer comparable yields to conventional metal-based systems but also significantly reduce reaction time and waste. The organocatalysts could be easily recovered and reused without notable loss in activity. Furthermore, the reactions proceeded with high selectivity and under ambient conditions, highlighting their potential for large-scale sustainable synthesis.

This work contributes to the advancement of green organic synthesis by integrating renewable resources and minimizing environmental impact. The application of such catalysts could transform the way fine chemicals are synthesized, aligning laboratory practices with the global agenda of sustainability and eco-efficiency. Future research will focus on expanding the substrate scope and exploring asymmetric versions of the studied reactions.
