Abstract
Chemical and spectroscopic evidence for the structure 1 of the dimer of 3-hydroxy-2,3-dimethyl-indolenine is presented. This evidence is based mainly on a comparison of the spectroscopic properties and reactions of both the dimer 1 and its hexadeutero analog 13. The stereochemistry derived by consideration of n.m.r. shielding is that found by the X-ray analysis of other investigators. The various ways in which this dimer can arise are discussed critically.Keywords
