Kinetics of Ru (III) catalyzed oxidation of aliphatic ketones such as acetone, ethyl methyl ketone, diethyl ketone, iso-butylmethyl ketone by N-bromosuccinimide in the presence of Hg(II) acetate have been studied in aqueous acid medium. The order of [N-bromosuccinimide] was found to be zero both in catalyzed as well as uncatalyzed reactions. However, the order of [ketone] changed from unity to ...

Suitably ortho-substituted iodobenzenes act as organocatalysts for the transfer of electrophilic bromine from N-bromosuccinimide to alkenes via the intermediacy of bromoiodinanes.

Diisopropylsilyl ethers were activated with N-bromosuccinimide, and reacted with a fluorous-tagged alcohol, to yield tethered substrates for ring-closing metathesis reactions.

One of the most widely used methods for the determination of amino acids is the ninhydrin technique perfected by Van Slyke and his coworkers (1). This permits the measurement of amino acid concentration either calorimetrically or by the volume of carbon dioxide released during the reaction. The measurement of carbon dioxide by the Van Slyke manometric apparatus is capable of great precision but...

In previous papers from this laboratory (1, 2) it has been reported that a-amino acids undergo a quantitative decarboxylation.in aqueous solution when treated with N-bromosuccinimide. Under the conditions used\ (a temperature of 30” and a pH of 3 to 5), the reaction was complete in 30 minutes. Anomalies in behavior were observed with glycine and /3-alanine. The consumption of N-bromosuccinimide...

The heterogeneity of the lysine-rich histone from several mammalian cells has been studied. The molecules were cleaved with N-bromosuccinimide and separated into three fractions by exclusion chromatography. The three fractions were Fraction 1, the NHz-terminal peptide of molecular weight -6000 which proved to be highly heterogeneous upon electrophoretic analysis; Fraction 2, the COOH-terminal f...
