Fast oxidation of secondary alcohols by the bromate-bromide system using cyclic microwave heating in acidic water
We report an improved, gentle, cyclic microwave activation technique for the oxidation of secondary alcohols using nonhazardous hypobromous acid (BrOH) as the reagent in acidic water. Several aliphatic and aromatic secondary alcohols were successfully oxidized to the corresponding ketones using this technique in high yields and with only minor amounts of side products.

A mild and efficient procedure for α-bromination of ketones using N-bromosuccinimide catalysed by ammonium acetate
Cyclic ketones reacted with N-bromosuccinimide (NBS) catalysed by NH 4OAc in Et2O at 25°C to give the corresponding α-brominated ketones in good yields, while acyclic ketones were efficiently brominated in CCl4 at 80°C.

PREPARATION OF vic-MERCAPTOISOPENTANOLS
This paper describes the preparation of some mercaptoisopentanols: 2-mercapto-3-methyl-1-butanol (I), 1-mercapto-3-methyl-2-butanol (II), 3-mercapto-3-methyl-2-butanol (III) and the unsaturated analogue of compound I - 2-mercapto-3-methyl-2-buten-1-ol (IV).These compounds belong to the flavonoid group present in food responsible for deterioration of their gustatory properties.
