From 2-aminobenzophenone (3a) it is possible to prepare quinoline la with the highest selectivity (86%) as compared with other mesoporous acidic catalysts. In contrast, the reaction catalyzed by amine-grafted SBA-15 yielded selectively (98%) the corresponding quinolone 2a in accordance with our previous results. Experimental results have been justified by theoretical calculations as function of the stability of reaction intermediate species, which could be involved in the process. (C) 2011 Elsevier B.V.
