The chemistry of „Dinaphthyldiquinhydrone”

Abstract

„Dinaphthyldiquinhydrone” (4) first obtained byStenhouse andGroves2 reacts as well as 4,4′-bi-(1,2-naphthoquinone)1 with aniline and substituted anilines to give anilinoquinones2 a-h. However, yields of2 are considerable higher if4 is used. The IR-Spectrum of4 is very similar to that of 2,11-dihydroxy-3,10-perylenquinone, therefore we suggest for4 a the structure of a 3,3′-dihydroxy-4,4′-dioxo-1,1′, 4,4′-tetrahydro-1,1′-binaphthylidene, at least in the solid state.
