2,6-Dimethylnaphthalene is mainly used for the preparation of 2,6-naphthalenedicarboxylic acid by oxidation of 2,6-dimethylnaphthalene in the liquid phase. 2,6-Naphthalenedicarboxylic acid is a monomer for the production of high-performance polymers, in particular poly (ethylene-2,6-naphthalene dicarboxylate) or shorter polyethylene naphthalate (PEN).

The last two isomers of DMMDA are 5,6-dimethoxy-2,3-methylenedioxy-1-α-methylphenylethylamine and 4,6-dimethoxy-2,3-methylenedioxy-1-α-methylphenylethylamine. Like all other α-methylphenylethylamine derivative compounds, DMMDA and its regioisomer have two enantiomers due to the methyl group being in the alpha position of the ethyl group in ...
It was first prepared by Robert Evert and Victor Merz in 1876 by hydrolysis of 2,6-dicyanonaphthalene. [2] [3] 1,8-Naphthalenedicarboxylic acid can be isomerized to 2,6-naphthalenedicarboxylic acid via the intermediacy of the dipotassium dicarboxylates. [2] It is also produced by oxidation of 2,6-diisopropylnaphthalene. [4]
DMMDA-2 is a bioactive phenethylamine discussed by Alexander Shulgin in his book PiHKAL (Phenethylamines i Have Known And Loved); however, he was not the first to synthesize it. [1] Shulgin comments in his book that a 50 milligram dose of DMMDA-2 produces similar effects to 3,4-methylenedioxy-1-α-methylphenylethylamine . [ 1 ]
Synthesis of symmetric and unsymmetric NDIs. NTCDI is redox-active, forming stable radical anions at –1.10 V vs. Fc/Fc + in Dichloromethane. [5] Its ability to accept electrons reflects the presence of an extended conjugated ring system and the electron withdrawing groups (carbonyl centers).
A solution of lithium naphthalenide, the lithium salt of naphthalene, in tetrahydrofuran. The alkali metal naphthalene salts are prepared by stirring the metal with naphthalene in an ethereal solvent, usually as tetrahydrofuran or dimethoxyethane. The resulting salt is dark green. [2] [3] [4] The anion is a radical, giving a strong EPR signal ...
Diaminonaphthalene describes several isomers containing naphthalene substituted with two amine groups (NH 2), also called naphthalenediamines. All isomers are white solids that tend to air-oxidize. The 2,3-, 1,5-, and 1,8- derivatives have attracted most attention. 1,2-Diaminonaphthalene 938-25-0 [1] 1,3-Diaminonaphthalene 24824-28-0 [2]
DMTMM (4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methyl-morpholinium chloride) is an organic triazine derivative commonly used for activation of carboxylic acids, particularly for amide synthesis. Amide coupling is one of the most common reactions in organic chemistry and DMTMM is one reagent used for that reaction.
