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 ...
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 ...
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.
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.
4-MeO-MiPT, or 4-methoxy-N-methyl-N-isopropyl tryptamine, is a lesser-known psychedelic drug. It is the 4-methoxy analog of MiPT . 4-MeO-MiPT was first synthesized by Alexander Shulgin and is mentioned in his book TiHKAL ( Tryptamines i Have Known And Loved ).
