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). [4]
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]
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 ...
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 ]
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 ...
DMCM (methyl 6,7-dimethoxy-4-ethyl-β-carboline-3-carboxylate) is a drug from the β-carboline family that induces anxiety and convulsions by acting as a negative allosteric modulator of GABA A receptors — functionally opposite to benzodiazepines and related drugs which are positive allosteric modulators — and is used in scientific research for these properties to test new anxiolytic and ...
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).
[1] [2] It is the 6-methoxy derivative of the serotonergic psychedelic N,N-dimethyltryptamine (DMT) and is a positional isomer of the serotonergic psychedelic 5-MeO-DMT. [3] Similarly to analogues like DMT and 5-MeO-DMT, 6-MeO-DMT acts as a serotonin 5-HT 2A receptor agonist as well as a non-selective agonist of many other serotonin receptors.
