Benzyl chloride

Share definition Flag
Benzyl chloride (BnCl) is a molecule that is a used to make pharmaceuticals and can also be used to make Phenyl-2-Propanone. Benzyl chloride is synthesized from toluene (benzyl hydride) by chlorination with TCCA (trichloroisocyanuric acid, pool chlorine) in sunlight with lithium bromide as a catalyst. The lithium bromide makes it so that you get benzyl chloride in hours instead of days. Phenyl-2-Propanone is synthesized by adding benzyl chloride in diethyl ether (or even better, dibutyl ether for higher yield) and adding magnesium turnings. You make benzyl magnesium chloride. Then you react it with acetonitrile and then do a hydrochloric acid work-up to get Phenyl-2-Propanone.

3,4-Methylenedioxybenzyl chloride 

Share definition Flag
3,4-Methylenedioxybenzyl chloride (MDBnCl; Piperonylchloride; Sesamyl methyl chloride; 3,4-Methylenedioxyphenyl methyl chloride) is a chemical that is used in organic synthesis. It's melting point is 20.5 °C. It's boiling point is 97-100 ° at 1 mmHg. MDBnCl is used to synthesize other chemicals like MDP2P (3,4-MethyleneDioxyPhenyl-2-Propanone) and MDP2Bu 3,4-MethyleneDioxyPhenyl-2-Butanone; 1-(3,4-Methylenedioxy)phenyl-2-butanone via MDBn-MgCl (3,4-Methylenedioxybenzyl magnesium chloride) and acetonitrile or propionitrile and HCl acid work-up.
3,4-Methylenedioxybenzyl chloride is very useful in the laboratory.

Ethyl Chloride

Share definition Flag
Ethyl chloride (EtCl, Chloroethane), is a chemical compound with chemical formula CH3CH2Cl, once widely used in producing tetraethyllead, a gasoline additive. It is a colorless, flammable gas or refrigerated liquid with a faintly sweet odor. Ethyl chloride is a lab solvent and an intermediate in the synthesis of 2-methyl-2-butanol through the formation of the grignard reagent, ethyl magnesium chloride and a grignard reaction with acetone, followed by hydrochloric acid work-up to yield 2-methyl-2-butanol. Ethyl chloride is synthesized by reacting ethanol with hydrochloric acid and zinc chloride catalyst. Ethyl chloride can also be used along with calcium hydroxide, sodium hydroxide, or potassium hydroxide to extract freebase arecoline out of the betel nut. Then react it with HBr (Hydrogen Bromide) to get Arecoline Hydrobromide.

I reacted ethanol with hydrochloric acid and a zinc chloride catalyst. I got ethyl chloride. I then extracted freebase arecoline from the betel nut and reacted it with hydrogen bromide gas to get Arecoline Hydrobromide.

I took some ethyl chloride and added anhydrous diethyl ether and magnesium turnings to get ethyl magnesium chloride. Then I reacted the Et-MgCl (ethyl magnesium chloride) with acetone. Then I took the 2m2bO-MgCl (2-methyl-2-butoxymagnesium chloride) and reacted it with hydrochloric acid to get 2-methyl-2-butanol.
