abstract: 5-Isothiocyanato-1,3-dioxo-2-p-tolyl-2,3-dihydro-1H-benz[de]isoquinoline (= 5-isothio-cyanato-1,8-naphthalenedicarbox-4-methylphenylimide, compd.5) was synthesized from 1H,3H-naphtho(1,8-cd)pyran-1,3-dione (= 1,8-naphtha-lenedicarboxylic anhydride, compd.1) through nitration, condensation with p-toluidine, reduction with tin(II)-chloride yielding 5-amino-1,3-dioxo-2-p-tolyl-2,3-dihydro-1H-benz(de)isoquino-line (4) as intermediate, and condensation with thiophosgene. Compd. 5 can be used for qualitative and quantitative analyses of compounds containing amino groups.
