Understanding an old dog’s tricks: The coupling of selective C–H activation with O2 by Co(salen).

The electrochemical behavior of a modified carbon paste electrode (MCPE) with N,N′ethylenbis(salicylideneiminato)copper(II) complex ([Cu(II)-Salen]) was investigated as a newsensor for cystein. The Britton-Robinson buffer with pH 5, 10% modifier in electrode, potentialscanning rate of 20 mVs-1 and puls height of 50 mV were used as the optimum condition for thedetermination of cysteine using car...

The title compound, (C(2)H(10)N(2))[Ni(C(16)H(14)N(2)O(2))](4)(ClO(4))(2)·C(3)H(7)NO, crystallizes with four Ni(salen) mol-ecules {salen is 2,2'-[ethane-1,2-diylbis(nitrilo-methyl-idyne)]diphenolate}, one ethyl-enediammonium cation (actually two half-cations, each located on a center of inversion), two perchlorate anions and one dimethyl-formamide solvent mol-ecule in the asymmetric unit. Each ...

Tandem mass spectrometric techniques in combination with high-level quantum chemical calculations have been employed to study the coordination chemistry of manganese– and oxomanganese–salen complexes in the gas phase. Electrospray ionization was used to transfer the ionic complexes from solution to the gas phase. The formation of fiveversus six-coordinate manganese(III) species was subsequently...

As part of our ongoing interest in the supramolecular chemistry of fluorinated organomercurials, we have investigated the interaction of bis(pentafluorophenyl)mercury ((C6F5)2Hg), and trimeric (perfluoro-o-phenylene)mercury ([o-C6F4Hg]3), with nickel(II) N,N'-bis(salicylidene)ethylenediamine) (Ni(salen)). While solution studies monitored by UV-VIS spectroscopy suggest that Ni(salen) interacts w...
