COA of Formula: C24H40N4O4Rh2. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: Dirhodium(II) tetrakis(caprolactam), is researched, Molecular C24H40N4O4Rh2, CAS is 138984-26-6, about Efficient Aziridination of Olefins Catalyzed by Mixed-Valent Dirhodium(II,III) Caprolactamate. Author is Catino, Arthur J.; Nichols, Jason M.; Forslund, Raymond E.; Doyle, Michael P..
A mild, efficient, and selective aziridination of olefins catalyzed by dirhodium(II) caprolactamate [Rh2(cap)4·2CH3CN] is described. Use of p-toluenesulfonamide, N-bromosuccinimide, and potassium carbonate readily affords aziridines in isolated yields of up to 95% under extremely mild conditions with as little as 0.01 mol % Rh2(cap)4. Aziridine formation occurs through Rh25+-catalyzed aminobromination and subsequent base-induced ring closure. An X-ray crystal structure of a Rh25+ halide complex, formed from the reaction between Rh2(cap)4 and N-chlorosuccinimide, has been obtained.
