The selective monobromination of various deactivated anilines using potassium bromide and sodiumperborate 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.

Scandium Triflate Catalyzed Tandem Transfer Hydrogenation and Cyclization Reaction of <i>o</i>-Aminobenzaldehydes and <i>o</i>-Aminoacetophenone with Alcohols
An effective Sc-catalyzed transfer hydrogenation and cyclizationtandemreaction has been achieved. This process showed excellent functional group compatibility and good yields. A variety of benzoxazines were produced with primary or secondary alcohols as a hydrogen source. Furthermore, the utility of this newly developed protocol is demonstrated through scaled-up experiment, late-stage modification

Abstract A Pd-catalyzed enantioselective synthesis of 2-methyl-3-methyleneindoline in up to 89% yield and 84% ee from racemic vinyl benzoxazinanones has been developed with the help of (R,R)-BenzP* ligand. Mechanism studies support the formation of palladacyclobutane as the key intermediatevia C2 attack to π-allyl Pd complex. The β-hydride elimination provides a new reaction pathway for the palladacyclobutane
