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

SNW-1, 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.

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.
