A metal and base free synthesis of primary amines has been developed at ambient temperature through ipso amination of diversely functionalized organoboronic acids, employing a combination of [bis(trifluoroacetoxy)iodo]benzene (PIFA)-N-bromosuccinimide (NBS) and methoxyamine hydrochloride as the aminating reagent. The amines were primarily obtained as their trifluoroacetate salts which on subseq...

Poly (N-bromosuccinimide) (PNBS) as a mild, efficient, non-acidic, polymeric and heterogeneous catalyst was applied for simple conversion of epoxides into thiiranes by treatment with KSCN or (NH2)2CS at room temperature. Aliphatic and aromatic epoxides converted into their corresponding thiiranes under mild conditions. All reactions proceeded in short reaction times and afforded the correspondi...

Michael addition–halogenation–intramolecular ring-closing (MHIRC) reactions are processes in which a halogen atom as leaving group can attach to substrates or reactants during the reaction, then undergoes intramolecular ring closure. In this communication MHIRC transformation of 4-benzylidene-3-phenylisoxazol-5(4H)-one and 1,3-dimethylbarbituric acid presence N-bromosuccinimide sodium acetate E...
