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.
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 ...
Tris(4-methoxyphenyl)phosphine is the organophosphorus compound with the formula (CH 3 OC 6 H 4) 3 P. Several isomers of this formula are known, but the symmetrical derivative with methoxy groups in the 4-position is most studied. The compound is used as a ligand in organometallic chemistry and homogeneous catalysis. [1]
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 ...
Methoxychlor was used to protect crops, ornamentals, livestock, and pets against fleas, mosquitoes, cockroaches, and other insects. It was intended to be a replacement for DDT, but has since been banned for use as a pesticide based on its acute toxicity, bioaccumulation, and endocrine disruption activity.
The methoxy group promotes highly regioselective additions. The diene is known to react with amines, [5] aldehydes, alkenes and alkynes. [4] Reactions with imines [6] and nitro-olefins [7] have been reported. It was first synthesized by the reaction of trimethylsilyl chloride with 4-methoxy-3-buten-2-one and zinc chloride: [8] Danishefsky's diene
