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]
2,5-Dimethoxy-4-cyanoamphetamine (DOCN) is a serotonergic drug of the phenethylamine, amphetamine, and DOx families. [1] [2] [3] It is a DOx derivative with a cyano group (–C≡N) at the 4 position of the molecule. [1] [2] [3] The drug shows much lower affinities for the serotonin 5-HT 2 receptors than other DOx drugs.
The diamine can also be produced by reaction of the 1,8-diol with ammonia at high temperatures. The peri-naphthalene 1-amino-naphthalene-8-sulfonic acid is a precursor to other peri-naphthalenes. It is prepared by nitration of naphthalene-1-sulfonic acid followed by reduction. Diazotization followed by loss of N 2 gives the naphthosulfone. This ...
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).
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 ...
1,8-Bis(dimethylamino)naphthalene is an organic compound with the formula C 10 H 6 (NMe 2) 2 (Me = methyl). It is classified as a peri-naphthalene , i.e. a 1,8-disubstituted derivative of naphthalene .
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 ...
