Studies on the Doebner-Miller, Skraup, and Related Reactions. IV. Intermediates and By-products in the Preparation of 1,10-Phenanthrolines

Abstract

Three β-arylaminoketones, intermediates in the syntheses of alkyl-1,10-phenanthrolines from 8-aminoquinolines, have been isolated. The isolation of two 1,2,3,4-tetrahydro-1,10-phenanthroline derivatives following cyclization reactions is also reported.
