Ni-thiosaccharinate complexes: Synthesis, characterization and DFT studies. Biological properties as superoxide dismutase mimetics and as anti-carcinogenic agents
(Elsevier Science SA, 2019-08-01)
This report describes the synthesis and characterization of two nickel thiosaccharinate complexes, [Ni(tsac)2(PPh3)2] (1) and [Ni(tsac)2(dppe)]·CH3CN (2), where tsac = thiosaccharinate anion, PPh3 = triphenylphosphane and ...
New insights into frustrated Lewis pairs: structural investigations of intramolecular phosphane-borane adducts by using modern solid-state NMR techniques and DFT calculations
(American Chemical Society - ACSWashington, DC, 2012-03)
Covalent bonding interactions between the Lewis acid and Lewis base functionalities have been probed in a series of “frustrated Lewis pairs” (FLPs) (mainly substituted vinylene linked intramolecular phosphane–borane adducts), ...
Four novel mononuclear and polynuclear Cu(I) thiosaccharinates with triphenylphosphane and bis(diphenylposphino)methane. Synthesis and structural study of Cu(4)(tsac)(4)(PPh(3))(3), Cu(tsac)(PPh(3))(2), Cu(4)(tsac)(4)(dppm)(2), and Cu(2)(tsac)(2)(dppm)(2)
(ELSEVIER SCIENCE SA, 2009)
Four new ternary complexes of copper(I) with thiosaccharin and phosphanes were prepared. The reaction of [Cu(4)(tsac)(4)(CH(3)CN)(2)] (1) (tsac: thiosaccharinate anion) with PPh(3) in molar ratios Cu(I)/PPh(3) 1:075 and ...
Nucleophilicity scale for n- and pi-nucleophiles
(ELSEVIER, 2006-08-31)
A recently introduced empirical nucleophilicity index for a series of n- and pi-nucleophiles was evaluated. The index is based on the frontier molecular orbital information of the nucleophile and its electrophilic partner. ...
Nucleophilicity scale for n- and π-nucleophiles
(2006)
A recently introduced empirical nucleophilicity index for a series of n- and π-nucleophiles was evaluated. The index is based on the frontier molecular orbital information of the nucleophile and its electrophilic partner. ...
Crystal structures and Hirshfeld surface analysis of [κ2-P,N-{(C6H5)2(C5H5N)P}Re(CO)3Br]·2CHCl3 and the product of its reaction with piperidine, [P-{(C6H5)2(C5H5N)P}(C5H11N)Re(CO)3Br]
(Acta Crystallographica Section E: Crystallographic Communications, 2019)
The coordination of the ligands with respect to the central atom in the complex bromidotricarbonyl[diphenyl(pyridin-2-yl)phosphane-κ2 N,P]rhenium(I) chloroform disolvate, [ReBr(C17H14NP)(CO)3]·2CHCl3 or [κ2-P,N-{(C6H5)2( ...
Remarkable coordination behavior of alkyl isocyanides toward unsaturated vicinal frustrated P/B Lewis pairs
(Royal Society of Chemistry - RSCCambridge, 2013-04)
The conjugated frustrated phosphane/borane Lewis pairs formed by 1,1-carboboration of a substituted diphenylphosphino acetylene, undergo a synergistic 1,1-addition reaction to n-butyl isocyanide with formation of new B-C ...
Reversible S-S Bond Breaking and Formation in Disulfide-containing Dinuclear Complexes of Mn(I)
(Wiley VCH Verlag, 2001-12)
An isolated reaction intermediate in the desulfurization of thiones promoted by phosphanes is provided by the ylide derivative 3, which is obtained by thiophilic addition of PCy3 to 2. Complex 2 is formed from the ...
Synthesis, crystal structures, antimicrobial, antifungal and antituberculosis activities of mixed ligand silver(I) complexes
(2013-10-14)
The biological activity of some new mixed silver-phosphane-thio-ligand complexes, with 1:1:2, 1:1:1 and 1:2:1 (Ag:phospine:ligand) compositions, have been examined. Ten compounds were prepared using a series of silver(I) ...
