A set of Cu(I) complexes with 3,7-diacetyl-1,3,7-triaza-5-phosphabicyclo-[3.3.1]nonane (DAPTA) phosphine ligands viz. [CuX(κP-DAPTA)3] (1: X = Br; 2: I) and [Cu(μ-X)(κP-DAPTA)2]2 (3: 4: were immobilized on activated carbon (AC) multi-walled nanotubes (CNT), as well these materials after surface functionalization. The copper(I) have shown favorable catalytic activity for the one-pot, microwave-a...

Summarization of electronic discussion fora is a unique challenge; techniques that work startlingly well on monolithic documents tend to fare poorly in this informal setting. Additionally, conventional techniques ignore much of the structures that have the potential to serve as valuable features in the summarization task. We present several novel examples of such features, including the catalys...

Abstract Great attention has been paid to cofacial porphyrins due their many unique advantages over monomeric analogs. However, synthesis is usually complicated. In this work, a facile impregnation method for preparing heterogenized, cofacially stacked proposed. An anionic porphyrin introduced as an underlayer immobilization of cationic cobalt via electrostatic force. The metal center the under...

In the present work, highly efficient oxidation of sulfides catalyzed by MoO2(acac)2 supported on multi-wall carbon nanotubes, MWCNTs, modified with 1,2-diaminobenzene (DAB) and 2-aminophenol (AP), at room temperature are reported. The effects of various parameters such as reaction time, solvent, catalyst amount, oxidant, etc, were studied. These heterogenized catalysts showed high activity in ...
