colorless to light yellow liquid | [Uses]
4-tert-Butylbenzyl bromide, a hydrophobic reactant, was used to keep the loaded mesoporous material particles under continuous stirring. | [General Description]
The nucleophilic substitution reaction of 4-tert-butylbenzyl bromide and potassium iodide was carried out in oil-in-water microemulsions based on various surfactants. | [Synthesis]
General procedure for the synthesis of 4-tert-butylbenzyl bromide from 4-tert-butyltoluene: Referring to Example 19 Preparation of N-(4-tert-butylbenzyl)methanamine (Alternative method), 4-tert-butyltoluene (14.8 g, 0.10 mol) was dissolved in carbon tetrachloride, and N-bromosuccinimide (17.8 g, 0.10 mol) and benzoyl peroxide (200 mg) were added . The reaction mixture was refluxed for 2 h and subsequently cooled to room temperature. The insoluble material was removed by filtration and the filtrate was washed with carbon tetrachloride. The filtrate was concentrated under reduced pressure and the resulting residue was dissolved in hexane and dried with magnesium sulfate. Finally, the solvent was evaporated under reduced pressure to give 22.7 g of 4-tert-butylbenzyl bromide (yield: 100%). | [References]
