Pyrrolidin-2-ones react with formaldehyde and chlorotrimethylsilane to give 1-chloromethylpyrrolidin-2-ones which upon subsequent reaction with primary and secondary amines give 1-aminomethylpyrrolidin-2-ones in good yield.
Electrochemical Generation of Hypervalent Bromine(III) Compounds
In sharp contrast to hypervalent iodine(III) compounds, the isoelectronic bromine(III) counterparts have been little studied to date. This knowledge gap is mainly attributed to the difficult-to-control reactivity of λ3-bromanes as well as to their challenging preparation from the highly toxic and corrosive BrF3 precursor. In this context, we present a straightforward and scalable approach to chelation-stabilized
