RCH=CH 2 + HBr → RCHBrCH 3. Under free radical conditions, the direction of the addition can be reversed. Free-radical addition is used commercially for the synthesis of 1-bromoalkanes, precursors to tertiary amines and quaternary ammonium salts. 2-Phenethyl bromide (C 6 H 5 CH 2 CH 2 Br) is produced via this route from styrene.
2-Phenylethyl bromide is an organobromide with the formula C 6 H 5 CH 2 CH 2 Br. It is a colorless liquid, although older samples appear yellow. Analogous to the preparation of most 1-bromoalkanes, it is prepared by free-radical addition of hydrogen bromide to styrene. These conditions lead to anti-Markovnikov addition, giving the 1-bromo ...
Bromomethane, commonly known as methyl bromide, is an organobromine compound with formula C H 3 Br. This colorless, odorless, nonflammable gas is produced both industrially and biologically. This colorless, odorless, nonflammable gas is produced both industrially and biologically.
Phenethyl alcohol, or 2-phenylethanol, is an organic compound with the chemical formula C 6 H 5 CH 2 CH 2 OH. It is a colourless liquid with a pleasant floral odor. It is a colourless liquid with a pleasant floral odor.
In the CF 3 radical the fluorine atom is an electron-withdrawing group via the inductive effect but also a weak pi donor through interaction of the fluorine lone pair with the radical center's SOMO. Compared to the methyl radical the CF 3 radical is pyramidal (angle 107.8 °C ) with a large inversion barrier, electrophilic and also more
3-Methylfentanyl (3-MF, mefentanyl) is an opioid analgesic that is an analog of fentanyl. 3-Methylfentanyl is one of the most potent opioids, estimated to be between 400 and 6000 times stronger than morphine, [1] depending on which isomer is used (with the cis isomers being the more potent ones).
A study by Graham and co-workers at the Upjohn Co., comparing many β-methylphenethylamines substituted on the benzene ring showed that β-methylphenethylamine itself had 1/700 x the pressor activity of epinephrine, corresponding to ~ 1/3 the potency of amphetamine. The β-methyl compound also had ~ 2 x the broncho-dilating power of amphetamine ...
