Imino phenoxide complexes of Nb and Ta show precise control towards the solvent free ring-opening polymerization of lactides (LA) and ε-caprolactone (CL). There is a close proximity between the observed number average molecular weight (M... more
A complete library of new alkoxides containing group 4 metals and the imino phenol ligand were synthesized in high yields and purity. These compounds showed catalytic activity towards the polymerization of L-lactide (L-LA), rac-lactide... more
Six different complexes containing bis(salphen) [salphen=N,N’-phenylenebis(salicylideneimine)] ligands were synthesized and characterized by various spectroscopic techniques and elemental analysis. In the presence of benzyl alcohol as an... more
An efficient and general protocol for intermolecular CN and CO cross-coupling of amines, alcohols, and phenols with halides has been developed by using AgNO3 as the catalyst and N,N-dimethylethylenediamine (N,N-DMEDA) as a ligand with... more
Complexes 1–7 were synthesized from tridentate half-salen ligands in good yields and purity. They were characterized by various spectroscopic techniques, elemental analyses, and X-ray crystallography. With titanium, homoleptic and... more
In the present study, we have discussed the bulk ring opening polymerization (ROP) of rac-lactide (rac-LA) and ε-caprolactone (ε-CL) using Cd(OAc)2. Cd(OAc)2 appeared to be a good catalyst for the polymerization of rac-LA and ε- CL... more
Air-Stable Palladium(0) Phosphine Sulfide Catalysts for Ullmann-Type C—N and C—O Coupling Reactions. — Phenyl bromide as reaction partner in amination and etherification gives similar (amination) or lower (etherification) yields at longer... more
A series of homoleptic iminophenoxide and bis(imino) phenoxide supported Zr and Hf complexes 1–10 has been synthesized and characterized by NMR, mass spectrometry and elemental analysis. Structural analysis of the selected complexes by... more
The preparation, structural characterization, luminescence, and catalytic activity of three palladium(II) complexes bearing imino phenoxide ligands are reported. The X-ray studies revealed that the complexes are mononuclear with palladium... more
Anion Exchange Membranes (AEM) can be used in fuel cells and electrolyzers. The benefits include lowering the amount of platinum catalysts, simplifying water management, and improving electrochemical kinetics at the air cathode. However,... more
Maleimides are known to be very good electrophiles, dienophiles, and dipolarophiles. In their Full Paper on page 586 ff., Pankaj Chauhan and Swapandeep Singh Chimni demonstrate that maleimide derivatives can be used as nucleophilic... more
Stable, non-hydrolysable, hydroxide-conducting polymers are of interest for electrochemical devices such as fuel cells, electrolyzers and flow-batteries. In this study, a series of tetrablock copolymers containing an all-hydrocarbon... more
The synthesis of homoleptic salalen ligand supported group 4 complexes and their applications in the ring-opening polymerization (ROP) of ε-caprolactone ( 3-CL) and lactide (LA) are described. All these complexes of type M(L)2 (LH ¼... more
A series of cross-linked (XL) anion-exchange membranes (AEMs) were synthesized on the basis of the ring opening metathesis polymerization (ROMP) of norbornene monomers (rPNB). Poly(bromopropyl norbornene)-block-poly(butyl norbornene)... more
Cross-linked (XL) anion-exchange membranes (AEMs) synthesized by vinyl addition polymerization of norbornene were prepared for use in anion-exchange membrane electrochemical devices, including fuel cells and electrolyzers. Tetrablock... more
