Abstract
Photocatalysts based on the immobilization of meso-TPP on lignin-nanoparticles were prepared and applied in the one-pot oxidative coupling of aromatic amines to N-alkyl imines. Heterogeneous catalysts were effective in both homocoupling and cross-coupling conditions, affording desired products in high yield. Among the immobilization procedures tested, the dialysis method afforded the most effective photocatalyst, which was characterized by the lower energy gap between the HOMO and LUMO of lignin. Lignin-nanoparticles alone showed the capacity to catalyze the oxidative coupling, suggesting the possibility of a synergy effect with immobilized meso-TPP. The sustainability of the procedure was confirmed by the use of the photocatalyst for more runs.
期刊介绍：
With an impact factor of 4.495 (2018), ChemCatChem is one of the premier journals in the field of catalysis. The journal provides primary research papers and critical secondary information on heterogeneous, homogeneous and bio- and nanocatalysis. The journal is well placed to strengthen cross-communication within between these communities. Its authors and readers come from academia, the chemical industry, and government laboratories across the world. It is published on behalf of Chemistry Europe, an association of 16 European chemical societies, and is supported by the German Catalysis Society.
