The synthesis of substituted 9-oxoacridan-4-carboxylic acids; part 3. The reaction of methyl anthranilates with diphenyliodonium-2-carboxylates was written by Rewcastle, Gordon W.;Denny, William A.. And the article was included in Synthesis in 1985.SDS of cas: 13420-63-8 This article mentions the following:
Twenty-two 9-oxoacridan-4-carboxylic acids I (R = H, 1-Me, 1-OMe, 1-Cl, 1-NO2, 1-CO2H, 2-Me, 3-Me, etc., R1 = H, R = H, R1 = 6-NH2, 6-Cl, 6-NO2, 7-NO2, 8-Me, 8-Cl) were prepared by cyclization of anilinobenzoates II followed by saponification II were prepared by treating diphenyliodonium-2-carboxylates III with Me anthranilates IV. In the experiment, the researchers used many compounds, for example, 2-Chloro-6-iodobenzoic acid (cas: 13420-63-8SDS of cas: 13420-63-8).
2-Chloro-6-iodobenzoic acid (cas: 13420-63-8) belongs to iodide derivatives. Organoiodine compounds occur widely in organic chemistry, but are relatively rare in nature. The C–I bond is the weakest of the carbon–halogen bonds. These bond strengths correlate with the electronegativity of the halogen, decreasing in the order F > Cl > Br > I. This periodic order also follows the atomic radius of halogens and the length of the carbon-halogen bond.SDS of cas: 13420-63-8
