Summary
The methods for the preparation and purification of the group of intermediate substances from naphthoquinone to 2− and 3− alkyl substituted naphthoquinones are described. The quinones prepared are: 2-ethyl-1,4-naphthoquinone, 2,3-dimethyl-1,4-naphthoquinone, 2-methyl-3-ethyl-1,4-naphthoquinone.
From such compounds, and from naphthoquinone and 2-methyl-1,4-naphthoquinone the corresponding hydroquinones and quinhydrones were prepared.
All quinones were identified by elemental analysis, I.R. and N.M.R. spectra. Their purity was tested by differential scanning calorimetry and gas chromatography. From all the data shown it is concluded that the compounds prepared have a purity not less than 99.5 mole%.
This investigation was financiatly supported by a grant of C.N.R. (National Research Council of Italy), which is gratefully acknowledges.
