The expression “organic catalyst” has recently been introduced to define an organic
compound (of relatively low molecular weight and simple structure) capable of promoting a …

The present review deals with the ring-opening of epoxides by various carbon, nitrogen,
oxygen, halogen, and sulfur-containing nucleophiles, which most of the resulting products …

Previously we found that covalent attachment of long‐chained, moderately hydrophobic
polycations to surfaces of solid objects renders the latter permanently bactericidal. Herein …

A series of polyacrylonitrile fiber-supported quaternary ammonium salts (PANF-QAS) were
prepared and applied to the catalytic reduction of aldehydes, ketones, azides, and benzyl …

An efficient and environmentally friendly process for the synthesis of β-hydroxy thiocyanates
from epoxides using NH4SCN and poly (ethylene glycol)-bound sulfonic acid as catalyst in …

B (HSO4) 3 was easily prepared and used as a novel and efficient solid acid catalyst for
conversion of epoxides to the corresponding thiocyanohydrins under solvent-free conditions …

An environmentally friendly water-based pathway to form the azide derivatives of soybean
oil and fatty esters is reported. This entails first the formation of epoxides and then the …

Magnetic nanoparticles-supported quaternary ammonium and phosphonium salts were
prepared and evaluated as phase-transfer catalysts. Some of them exhibited good activities …

Sarcophine (1), a cembranoid diterpene is known to inhibit the process of tumorigenesis.
Sarcophine can be isolated in large amounts from the Red Sea soft coral Sarcophyton …

ZnFe2O4 nanoparticles were synthesized and used as recyclable magnetic catalyst in the
solvent-free conversion of different epoxides to vicinal hydroxythiocyanates with NH4SCN at …
