Phenylpropiolic acids. VIII. Self-condensation of 3-halo-4-methoxyphenylpropiolic acids was written by Baddar, Fawzi G.;Moussa, G. E. M.;Omar, M. T.. And the article was included in Journal of the Chemical Society [Section] C: Organic in 1968.COA of Formula: C8H7IO2 This article mentions the following:
3-Halo-4-methoxyphenylpropiolic acids are converted by Ac2O into a mixture of 6- and 8-halo-7-methoxy-1-(3-halo-4-methoxyphenyl)naphthalene-2,3-dicarboxylic anhydrides. The structure of 6-bromo-7-methoxy-1-(3-bromo-4 – methoxyphenyl)naphthalene-2,3-dicarboxylic anhydride was established by its conversion into the corresponding 6,7-dimethoxy derivative The structure of the remaining anhydrides were established by ir and uv spectroscopy. The anhydrides are isomerized by AlCl3 to the corresponding 7H-benzo[c]fluoren-7-one. In the experiment, the researchers used many compounds, for example, 3-Iodo-4-methoxybenzaldehyde (cas: 2314-37-6COA of Formula: C8H7IO2).
3-Iodo-4-methoxybenzaldehyde (cas: 2314-37-6) belongs to iodide derivatives. Typical reactions of alkyl iodides include nucleophilic substitution, elimination, reduction, and the formation of organometallics. 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.COA of Formula: C8H7IO2
