1. Four-Step Synthesis of HDippL The initial step utilized pyridine and acetyl chloride to protect the alcohol functional group of 2,6-dimethyl phenol. The double bromination of the methyl substituents was then initially attempted at 90 °C using infrared activated N-bromosuccinimide (NBS).13 How...
The kinetics of bromination of several aromatic compounds (anilides, anisoles, and phenols) was investigated in 80% aqueous acetic acid (v/v) in the temperature range 20–50°C using N -bromosuccinimide (NBS) as the reagent. The reaction was found to be first order in the aromatic ...
and 4-t-butyl-7-methoxy-2-succinimidyl-2H-azepine by the respective reactions of 5-t-butyl-2-methoxy-3H-azepine with bromine and NBS suggests a plausible mechanism for the conversion of 3H-azepine to 2H-azepine as 1,4-addition of an electrophile and a consequent 1,2-dehydrobromination. Di...
the synthesis of 5-bromomethylpyridine-2,3-dicarboxylic acid methyl ester (CMPE) via a bromination reaction with 5-methylpyridine-2,3-dicarboxylic acid dimethyl ester (MPE) as the raw material, N-bromosuccinimide (NBS) as the brominating reagent, and azobisisobutyronitrile (AIBN) as an initiator...
The kinetics of the oxidation of aspirin (ASP) by bromamine-T (BAT), N-bromosuccinimide (NBS), and N-bromophthalimide (NBP) has been studied in aqueous perchloric acid at 303 K. The oxidation reaction follows identical kinetics with first-order in [oxidant], fractional-order in [ASP], ...
Bromination in the presence of pyridine, NBS, trimethyl phosphate, and iodination with ICl and ICl/pyridine has been also performed. A common SET mechanism may be proposed for both halogenations; depending on the reaction conditions, bromination can also occur via acid-catalysed or SE2 routes. ...
