One prominent application of synthetic organobromine compounds is the use of polybrominated diphenyl ethers as fire-retardants, and in fact fire-retardant manufacture is currently the major industrial use of the element bromine. 402-49-3, formula is C8H6BrF3, Name is 1-(Bromomethyl)-4-(trifluoromethyl)benzene, Electric Literature of 402-49-3
O’ Sullivan, Michael J.;Hatley, Richard J. D.;Wellaway, Christopher R.;Bew, Sean P.;Richards, Christopher J. research published 《 Synthetic approaches to N- and 4-substituted 1,4-dihydro-3(2H)-isoquinolinone derivatives》, the research content is summarized as follows. Reaction of methyl-2-(2-formylphenyl)acetate with primary amines in a reductive amination/cyclisation process resulted in N-substituted 1,4-dihydro-3(2H)-isoquinolinones I [R1 = allyl, propynyl, 2,2-dimethoxyethyl; R2= H, benzyl, 4-trifluoromethylbenzyl, etc]. With H2NCH2R sodium borohydride was a suitable reductant (11 examples), but H2NCHR1R2 required a transfer hydrogenation using ammonium formate catalyzed by palladium on carbon (9 examples). 4-Substituted-1,4-dihydro-3(2H)-isoquinolinones were synthesized by deprotonation (n-butyllithium) and addition of R3CH2Br (12 examples with R3 = alkyl, Ar, CH=CH2, CCH). Modest diastereoselectivity was achieved with 1,4-dihydro-3(2H)-isoquinolinones derived from H2NCHMeR2 [R2 = (η5-C5H4)Co(η4-C4Ph4) – maximum dr = 1.9 : 1], but use of H2NCHMeFc (Fc = ferrocenyl) provided a new method of 1,4-dihydro-3(2H)-isoquinolinone N-deprotection with formic acid.
402-49-3, 4-Trifluoromethylbenzyl bromide is a useful research compound. Its molecular formula is C8H6BrF3 and its molecular weight is 239.03 g/mol. The purity is usually 95%.
4-Trifluoromethylbenzyl bromide is a choline derivative that acts as an anticancer agent. It is structurally similar to the anticancer drug doxorubicin, which has been shown to be effective against breast cancer and leukemia. 4-Trifluoromethylbenzyl bromide interacts with cellular proteins, including choline kinase, and inhibits the mitochondrial pathway. This leads to cell death through apoptosis. The molecule also interacts with nucleotide bases such as thymine and cytosine in DNA, inhibiting transcription and replication. 4-Trifluoromethylbenzyl bromide binds strongly to the hydroxyl group of cholesterol by an electrophilic substitution mechanism to form a covalent bond with its hydroxy group. The molecule can also bind to chloride ions by an ionic bond., Electric Literature of 402-49-3
