YL-N-(2-SUBSTITUTED-9-ACRIDINYL)IMINOTHIOCARBONATE AND YL-N-(4-SUBSTITUTED-9-ACRIDINYL)IMINOTHIOCARBONATE - NEW REACTIVE INTERMEDIATES WITHFLUORESCENCE PROPERTIES

A series of O-methyl-S-allyl-N-(2- and 4-substituted 9-acridinyl)imino thiocarbonates IIIa-IIIe has been prepared in good yields by alkylatio n of corresponding sodium iminothiocarbonates IIa-IIe which were obtai ned by addition of sodium methoxide to 9-isothiocyanatoacridines Ia-Ie . Relative fluorescence intensity measurements of IIIa-IIIe showed tha t 2-methoxy derivative IIIb exhibited threefold higher intensity of fl uorescence than 9-isothiocyanatoacridine. The structure of IIIa-IIIe w as corroborated by the CHN elemental analysis, IR and mass spectra, an d completely assigned H-1 and C-13 NMR spectra.
