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]
Alternatively, benzene may react with carbon tetrachloride using the same catalyst to obtain the triphenylmethyl chloride–aluminium chloride adduct which is then treated with diethyl ether for 24 hours at room temperature and hydrolyzed with concentrated hydrochloric acid: [3] 3 C 6 H 6 + CCl 4 + AlCl 3 → Ph 3 CCl·AlCl 3 Ph 3 CCl·AlCl 3 ...
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 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.
It is used as an alkylating agent and industrial solvent to manufacture dodecylbenzyl chloride, water repellents, ion-exchange resins, polymers, and as a chloromethylation reagent. In organic synthesis the compound is used for the introduction of the methoxymethyl (MOM) protecting group .
This reaction can be optimized by carefully controlling the amount of organolithium reagent addition, or using trimethylsilyl chloride to quench excess lithium reagent. [40] A more common way to synthesize ketones is through the addition of organolithium reagents to Weinreb amides (N-methoxy-N-methyl amides).
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
4-Methoxyphencyclidine (methoxydine, 4-MeO-PCP) is a dissociative anesthetic drug that has been sold online as a research chemical. The synthesis of 4-MeO-PCP was first reported in 1965 by the Parke-Davis medicinal chemist Victor Maddox. [ 1 ]
