Schiff‐base Polymer Immobilized Ruthenium for Efficient Catalytic Cross‐coupling of Secondary Alcohols with 2‐amino‐ and γ‐aminobenzyl Alcohols to Give Quinolines and Pyridines

Abstract

A Schiff‐base porous polymer has been impregnated with ruthenium trichloride for acceptor‐free dehydrogenation coupling (ADC) of secondary alcohols with γ‐amino‐ and 2‐aminobenzyl alcohols to give pyridines and quinolines. This heterogenous catalyst exhibited high catalytic efficiency over repeated cycles with wide functional group tolerance.

Emerging trends in the development and applications of triazine-based covalent organic polymers: a comprehensive review

“…134 In 2024, Li et al synthesized RuCl 3 /SNW-1 by impregnating a Schiff base porous polymer, SNW-1, with RuCl 3 , wherein Ru 3+ cations were sequestered by N atoms of the polymer (Scheme 47a). 135 The PXRD pattern revealed the amorphous nature of SNW-1, which was retained even after impregnation with 2.5 wt% RuCl 3 . SEM images showed the porous architecture of the polymer, which was composed of irregularly shaped nanoparticles, with no discernible changes in the morphology upon loading with RuCl 3 .…”
