Synthesis, crystal structure, and electrochemical properties of two new manganese complexes with a ligand derived from 1,2-propanediamine and 2-hydroxy-5-methoxybenzaldehyde

Two new homo binuclear manganese(III) complexes, [Mn(L)(H 2O)]2(PF6)2, where [H2 L = N,N′-Bis(2-hydroxy-5-methoxybenzylidene)-propane-1,2-diamine] have been prepared by reaction of N,N′-bis(2-hydroxy-

Facile, efficient, and diastereoselective synthesis of heterohelicene-like molecules

A concise and efficient route to new and interesting heterohelicene-like molecules has been developed through the one-pot, cascade reductive coupling reaction of o-hydroxydiimines or o-nitrodiimines and triphosgene in the presence of TiCl4/Sm.

Synthesis, spectral, photolysis and electrochemical studies of mononuclear copper(II) complex with a new asymmetric tetradentate ligand: Application as copper nanoparticle precursor

A copper(II) complex with asymmetric tetradentate Schiff base ligand, obtained by the single condensation of 1,2-diaminopropane with 2-hydroxy-5-methoxy benzaldehyde was prepared. The ligand and complex were characterized by their IR, UV-Vis, FT-IR, NMR s

Mononuclear Mn(III) complexes have been prepared via the Mn(II) reaction of an equimolar of Schiff-bases derived from reaction of 2-hydroxy-3- methoxybenzaldehyde or 2-hydroxy-5-methoxybenzaldehyde with 1,2-diaminopropane. Axial ligands L include: pyridin

Salicylidene-imine-Zirconium(IV) Complexes in Combination with Methylalumoxane as Catalysts for the Conversion of Hexa-1,5-diene: Adjusting of the Catalytic Activity

A variety of substituted Schiff base complexes of the composition ("salen")ZrCl2(thf) (1-21) were synthesized, with methylalumoxane ("MAO") activated and used for a systematic study of their catalytic activity towards hexa-1,5-diene ("salen": substituted salicylidene-ethylene-iminato ligands). Main product of the catalytic cycle is methylenecyclopentane. Dimers are only formed in minor amounts. The catalytic activity and selectivity of the Ziegler-Natta systems strongly depend on the nature and the position of the peripheric substituents in the Schiff base ligands. Electron-withdrawing substituents in para-position to the phenolato oxygen (5-position) decrease the catalytic activity. Improved activity and selectivity were obtained with electron-donating substituents in 5-position. Altering the ethylene bridge causes a lowering of the activity or inactivation. According to the X-ray analysis the metal center in the related complex (L)ZrCl2 (22) (L: N′,N′-bis(ethylene)-N′-methyl-N,N″- bis(benzoylacetonatoimine) has a pentagonal-bipyramidal environment. The pentadentate Schiff base ligand lies in the plane, and both chloro groups occupy the axial positions. In contrast to the catalytically active salene complexes 22 can not rearrange to form a species in which the both chlorides are cis to each other. Consequently 22 is catalytically inactive.
