Reactions catalyzed interfaces commonly occur at high coverage and in condensed media, causing turnover rates to depend on composition, collectively referred to as solvent effects. In a patent，Which mentioned a new discovery about name: 5-(Bromomethyl)-2,3-dihydro-1,4-benzodioxine, name: 5-(Bromomethyl)-2,3-dihydro-1,4-benzodioxine
Substituted phenoxy-aminopropanols of the formula STR1 wherein R is a branched-chain alkyl of 3 or 4 carbon atoms, R 1 is hydrogen, halogen or lower alkyl and R 2 and R 3, independently, are hydrogen, halogen, lower alkyl, lower alkoxy or lower alkylthio, and pharmaceutically acceptable acid addition salts thereof, are described. A process for their preparation, as well as pharmaceutical preparations containing them are also described. The compounds of formula I and their salts possess cardioselective beta-adrenergic blocking activity and antihypertensive activity.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.name: 5-(Bromomethyl)-2,3-dihydro-1,4-benzodioxine, you can also check out more blogs about214894-89-0
