METHOD FOR SYNTHESIZING AROMATIC SODIUM COMPOUND

A technique that can synthesize an aromatic sodium compound easily, in a short time, and efficiently through a small number of steps is constructed. The invention comprises a step A in which, in a reaction solvent, an alkyl halide compound represented by general formula I (R1—X1) (wherein R1 is an alkyl group and X1 is a halogen atom) is reacted with a dispersion that is obtained by dispersing sodium into a dispersion solvent, thereby obtaining an alkyl sodium compound represented by general formula II (R1—Na) (wherein R1 is the same as R1 of general formula I); and a step B in which, a halogenated aromatic compound represented by general formula III (R2—X2) (wherein, in the formula, R2 is an aromatic group that may have a substituent that does not react with sodium, and X2 is a halogen atom) is added into the reaction solvent after the step A to react with the alkyl sodium compound represented by general formula II (R1—Na), which has been obtained in the step A, thereby performing halogen-sodium exchange and obtaining an aromatic sodium compound represented by general formula IV (R2—Na).

Nuclear Heptylation of Benzene and Naphthalene and Cyclopentylation of Toluene

Thermal decomposition of 1-, 2-, 3- and 4-heptyltoluene-p-sulphonates in the presence of aromatic substrates like benzene or naphthalene at 130-35 deg, affords differently substituted α- and β-isomers in the case of naphthalene.Skeletal isomerisation of the alkyl group is observed where different isomeric 1-, 2-, 3- and 4-heptyl-aromatics are obtained.Also thermal decomposition of cyclopentylmethane sulphonate in the presence of toluene at 130-35 deg, furnishes the corresponding o-, m- and p-substituted toluenes.The isomers have been identified and estimated quantitatively by GLC.
