TIPT3tren;(2,2′′,6,6′′-tetraisopropyl-1,3′:5′,1′′-terphenyland tren is tris(2-aminoethyl)amine)(tris(2-aminoethyl)amine);N',N'-bis[2-[3,5-bis[2,6-di(propan-2-yl)phenyl]anilino]ethyl]-N-[3,5-bis[2,6-di(propan-2-yl)phenyl]phenyl]ethane-1,2-diamine
Generation, Characterization, and Reactivity of a CuII–Alkylperoxide/Anilino Radical Complex: Insight into the O–O Bond Cleavage Mechanism
摘要:
The reaction of [Cu-I(TIPT(3)tren) (CH3CN)]ClO4 (1) and cumene hydroperoxide (C6H5C-(CH3)(2)OOH, ROOH) at-60 degrees C in CH2Cl2 gave a Cu-II- alkylperoxide/anilino radical complex 2, the formation of which was confirmed by UV vis, resonance Raman, EPR, and CSI-mass spectroscopy. The mechanism of formation of 2, as well as its reactivity, has been explored.
A stable nickel(II)-aminoxyl radical complex was generated by the reaction of a nickel(II) complex supported by a tren ligand (tris(2-aminoethyl)amine) having bulky m-terphenyl substituents (TIPT: 3,5-bis(2,6-diisopropylphenyl)phenyl) and m-CPBA (m-chloroperoxybenzoic acid). The formation mechanism of the nickel(II)-aminoxyl radical complex was examined.
