Two series of naphthalene-1,8-dicarboxylic acid derived compounds have been synthesized starting from commercially available 4-chloro-1,8-naphthalic anhydride first series, formally derived from 1,8-naphthalic anhydride, was prepared by treating 4-chloro-1,8-naphthalic anhydride 1 in N-methylpyrrolidone with cyclic secondary amines such as 4-methylpiperidine, 4-benzylpiperidine and 4 Author: Alina Nicolescu, Anton Airinei, Emilian Georgescu, Florentina Georgescu, Radu Tigoianu, Florin Oance.
/OTHER TOXICITY INFORMATION/ In a plant for the production of 1,8-naphthalic anhydride a total of 61 workers were employed in the period from to The workers were under the company physician's medical supervision.
They were not observed to develop any diseases with a causal relation to 1,8-naphthalic anhydride exposure.
The new naphthalic anhydride 6-(4-benzyl-piperazinyl)benzo[de]isochromene-1,3-dione (3) presents the highest value of fluorescence quantum yield in solvents with lower polarities.
The results demonstrate that the quantum yields values of naphthalic anhydride derivatives are higher than those of naphthalimide : Alina Nicolescu, Anton Airinei, Emilian Georgescu, Florentina Georgescu, Radu Tigoianu, Florin Oance.
A new direct synthesis of benzo(k,1)thioxanthene-3,4-dicarboxylic anhydride from 4-nitro-naphthalene-1,8-dicarboxylic anhydride and 2-aminobenzenethiol is reported; 4-(2-aminophenylthio) naphthalene-1,8-dicarboxylic anhydride and 4-phenylthionaphthalene-1,8-dicarboxylic anhydride are also by: mmol KOH and mmol of Naphthalene-1,8-dicarboxylic anhydride, was sealed in a 25 ml T eflonlined bomb at °C for 5 days and then cooled to room temperature.

Compared to the aza-Wittig reaction of aldehydes, ketones, amides, and esters, the aza-Wittig reaction of acid anhydride was always overlooked, which should be an important part of Wittig reactions. Here, the aza-Wittig reaction of anhydride and catalytic aza-Wittig reaction of anhydride were both developed with high yields, which provides an efficient method to synthesize of 4H-benzo[d][1,3 Cited by: Naphthalene-1,8-dicarboxylic acid, 1,8-Acid, cyclizes spontaneously in acidic aqueous solution to naphthalene-1,8-dicarboxylic anhydride, 1,8-An, and here we present an ab initio study of the.
