Triphenylmethylsodium can be prepared from trityl chloride dissolved in an aprotic solvent and sodium: [4] (C 6 H 5) 3 CCl + 2 Na → (C 6 H 5) 3 CNa + NaCl. Reaction with silver hexafluorophosphate gives triphenylmethyl hexafluorophosphate. Trityl chloride reacts with zinc in nonpolar solvents (e.g. benzene) to form Gomberg's dimer. [5]
Triphenylmethane was first synthesized in 1872 by the German chemist August Kekulé and his Dutch student Antoine Paul Nicolas Franchimont (1844–1919) by heating diphenylmercury (Hg(C 6 H 5) 2, Quecksilberdiphenyl) with benzal chloride (C 6 H 5 CHCl 2, Benzylenchlorid).
The reagent can be prepared in two steps from triphenylphosphine.The first step is P-alkylation with chloromethyl methyl ether.. PPh 3 + CH 3 OCH 2 Cl → [CH 3 OCH 2 PPh 3]Cl. In the second step, the resulting phosphonium salt is deprotonated.
5,7-Dihydroxy-6-methoxy-2(4-phenoxyphenyl)-4H-chromene-4-one (DMPC) is a derivative of oroxylin A. It has memory improving effects and can reduce ADHD-like behavior. It has memory improving effects and can reduce ADHD-like behavior.
In organic chemistry, a methoxymethyl ether is a functional group with the formula ROCH 2 OCH 3, abbreviated MOM.It is a kind of chloroalkyl ether and, like its congeners, often employed in organic synthesis to protect alcohols.
Walgreens plans to close hundreds of stores by the end of 2025 to turn around its flagging sales. It has already closed roughly 2,000 locations over the past decade and has "a lot of experience ...
3,4-Di methoxy phenethylamine (DMPEA) is a chemical compound of the phenethylamine class. It is an analogue of the major human neurotransmitter dopamine where the 3- and 4-position hydroxy groups have been replaced with methoxy groups. It is also closely related to mescaline which is 3,4,5-trimethoxyphenethylamine and to 3,4 ...
The triphenylmethyl radical can be prepared by homolysis of triphenylmethyl chloride 1 by a metal like silver or zinc in benzene or diethyl ether. The radical 2 forms a chemical equilibrium with the quinoid-type dimer 3 (Gomberg's dimer). In benzene the concentration of the radical is 2%. [3] Triphenylmethyl radical
