OSTI ID:5544859
A research program was established to find transition-metal catalysts that will regioselectively reduce the heterocyclic ring in polynuclear heteroaromatic nitrogen compounds. Some of the findings are: (1) quinoline, acridine, benzoquinolines and phenanthridine which are found in coal and coal liquids, can be selectively reduced under various homogeneous hydrogenation conditions, i.e., water gas shift (wgs), synthesis gas (sg) and hydrogerc alone using transition metal hydrides as catalysts; (2) Wilkinson's catalyst, ((C/sub 6/H/sub 5/)/sub 3/P)/sub 3/ RhCl can selectively reduce quinoline, 5,6- and 7,8-benzoquinoline, acridine and phenanthridine under mild conditions in nearly quantitative yields; (3) 9,10-dihydrophenanthridine can act as a hydrogen donor only in the presence of rhodium and ruthenium catalysts.
