DIMETHYL-2,2′-BIQUINOLYLS

Abstract

Catalytic dehydrogenation of 4-methylquinoline and 6-methylquinoline has been shown to give the corresponding dimethyl-2,2′-biquinolyls. The ultraviolet absorption spectra of the quinolines and biquinolyls have been measured, and the color reaction of the dimethylbiquinolyls with cuprous ion investigated. In all properties examined the dimethylbiquinolyls and biquinolyl behave in a parallel manner.
