Two new series of organic soluble indigoids 7-7′-dialkoxyindigoids (2a, 2b) and 4,4′-dibromo-7,7′-dialkoxyindigoids (3a, 3b) (alkoxy = n-butoxy and n-octyloxy) were synthesized starting from the inexpensive 3-hydroxybenzaldehyde. The indigoids

The ozonation catalyzed by iron-pillared clays was studied. The degradation of dye indigo carmine (IC) was elected as test reaction. Fe-pillared clays were synthesized by employing hydrolyzed FeCl3solutions and bentonite. The pillared structure was v

The oxidation of indigo carmine by potassium hexacyanoferrate(III) is catalyzed by trace of silver nanoparticle (AgNP). The reaction is followed UV-Vis absorption spectrophotometrically by measuring the change in the absorption spectra (λmax 612 nm)

When indigo is boiled with nitrobenzene, iodobenzene, potassium carbonate and copper bronze, it is transformed into a sticky mass, from which a small quantity of two acids can be isolated viz.: N-phenyl-anthranilic acid and bis-(l-phenyl-3-keto-indol

When indigo is suspended in dry chloroform and treated with ozone an ozonide is formed, which can be decomposed with water when it furnishes isatin. The same result is obtained when dry ethyl acetate is used but when indigo is ozonised in wet ethyl a

An attempt was made tot prepare N,N′-ethene indigo, the derivative of cis-indigo in which the nitrogen atoms are joined by an ethene link. A compound was however obtained whose probable formula is that of N,N′-ethene indigo with a molecule of wat

Attempts were made to prepare derivatives of indigo in which the nitrogen atoms are joined by a trimethylene, a hexamethylene or a decamethylene linkage. In every case pitch-like compounds were obtained which were green in colour and which dissolved
