ChemInform Abstract: Synthesis of Hydroxylated Binaphthoquinones via Amine/Hydroxyl Exchange ‐ Reaction of 2,2′‐Binaphthyl‐1,4;1′,4′‐diquinones with Piperidine.

Abstract The hydroxylation of dimeric naphthoquinones such as (I) can be achieved using three successive steps: 1. Addition of piperidine (II) to (I) gives the amines (III).
