Ozonolysis of primary aliphatic amines in fine particles

The ozonolysis of primary aliphatic amines in fine particles

The oxidative processing by ozone of the particulate amines octadecylamine (ODA) and hexadecylamine (HDA) is reported. Ozonolysis of these amines resulted in strong NO−2 and NO − 3 ion signals that increased with ozone exposure as monitored by photoelectron resonance capture ionization aerosol mass spectrometry. These products suggest a mechanism of progressive oxidation of the particulate amin...

An Efficient One Pot Procedure for Preparation of Symmetrical N,N'-Disubstituted Urea from Aromatic and Aliphatic Amines and Urea under Microwave Irradiation

A phosgene-free synthesis of symmetrical N,N'-disubstituted urea by the reaction of aromatic and aliphatic primary amines and urea promoted by  microwave irradiation in the presence of a suitable energy-transfer solvent such as N-N-dimethylacetamide is described.

Application of ZnO Nanorods for the Synthesis of Thiazole Derivatives via Multicomponent Reactions in Water

Simple three-component reactions between dialkyl acetylenedicarboxylate, primary amines and isothiocyanates in the presence of catalytic amount of ZnO nanorods are investigated in water at room temperature which produced thiazole derivatives in good yields.

One-pot highly efficient synthesis of substituted pyrroles and N-bridgehead pyrroles by zinc-catalyzed multicomponent reaction.

A convenient zinc(II) chloride-catalyzed regioselective propargylation/amination/cycloisomerization process has been developed for the synthesis of substituted pyrrole derivatives from propargylic acetates, enoxysilanes and primary amines. Various aromatic and aliphatic propargylic acetates participate well in the reaction, providing the propargylation/amination/cycloisomerization products in g...
