Crystal structure and characterization of L-arginine chlorate and L-arginine bromate
The salts L-arginine.HClO3 and L-arginine.HBrO3, were synthesized. The crystals obtained were characterized by IR and NQR spectroscopy, thermal analysis, Nd:YAG laser radiation second harmonic generation, dielectric, piezoelectric an
Aqueous Et4NBrO3/KBr as a versatile and environmentally benign source of bromine for the selective trans-bromination of alkenes
An aqueous solution of tetraethyl ammonium bromate and potassium bromide is found to be an environmentally benign source of bromine at ambient temperature. This reagent is used for selective trans-dibromination of several substituted alkenes. The reaction conditions are mild and the yield of the products are high and other possible by-products such as bromohydrin formation and aromatic substitution have not been observed.

The Disproportionation of HBrO2, Key Species of the Belousov-Zhabotinskii Oscillating Reaction
The rate constant of the disproportionation of HBrO2, 2HBrO2->HBrO3 + HOBr, an important step of the Belousov-Zhabotinskii oscillating system, was measured spectrophotometrically at 240 nm by using stopped-flow techniques.Its value at =0.5 M, T=24
