- The components of xRNA: Synthesis and fluorescence of a full genetic set of size-expanded ribonucleosides
-
The synthesis and properties of a full set of four benzo-expanded ribonucleosides (xRNA), analogous to A, G, C, and U RNA monomers, are described. The nucleosides are efficient fluorophores with emission maxima of 369-411 nm. The compounds are expected to

- Novel bromination method for anilines and anisoles using NH 4Br/H2O2 in CH3COOH
-
A simple, efficient, regioselective, environmentally safe, and economical method for the oxybromination of anilines and anisoles without catalyst is reported. The electrophilic substitution of bromine generated in situ from ammonium bromide as a bromine source and hydrogen peroxide as an oxidant for the first time.

- Mild and regioselective oxidative bromination of anilines using potassium bromide and sodium perborate
-
The selective monobromination of various deactivated anilines using potassium bromide and sodium perborate as oxidant has been achieved. The use of ammonium molybdate as catalyst accelerates the rate of reaction but is not essential to obtain good yields and high selectivities. (C) 2000 Elsevier Science Ltd.
