Phosphines are widely used ligands in transition metal-catalyzed reactions. Arylphosphines, such as triphenylphosphine, were among the first phosphines to show broad utility in catalysis. Beginning in the late 1990s, sterically demanding and electronrich trialkylphosphines began to receive attention as supporting ligands. These ligands were found to be particularly effective at promoting oxidative addition in cross-coupling of Read More

Macrocyclic compounds have attracted tremendous attention for their superior performance in supramolecular recognition, catalysis, and host-guest interaction. With these admirable properties, macrocyclic compounds were used as modifiers for enhancing the sensitivity and selectivity of electrodes and optical sensors. The classic macrocyclic compounds, including crown ethers, cyclodextrins, calixarenes, cucurbiturils, an Read More

The catalytic activity of silver and its salts in various reactions leads to a vast variety of organic compounds having significant applications in organic synthesis. This review gives a comprehensive study on silver-catalyzed multi-component reactions that attracted the interest of the scientific world through ecofriendly, atom-economic and mild conditions. The silver-catalyzed multi-component synthesis of organic com Read More

Molecular orbitals are critical in the rationalization of several chemical reactions. Thus, the frontier molecular orbital theory, proposed by Fukui's group, postulated the importance of the Highest Occupied Molecular Orbital (HOMO) and the Lowest Unoccupied Molecular Orbital (LUMO) for chemical reactions. It should be kept in mind, however, that there are limitations of this theory and new perspectives about the chemica Read More

A new tetra triazole functionalized calix[4]resorcinarene macrocycle (5) is synthesized and utilized for the detection of copper ions in the aqueous medium. The photophysical potential of compound (5) is examined by a range of cations (Ba2+, Ca2+, Co2+, Hg2+, K+, Mg2+, Mn2+, Na+, NH4 + and Pd2+). The triazole based calix[4]resorcinarene macrocycle (5) has interacted with Cu2+ ion in preference of other cations. A signifi Read More
