Synthesis of 1-benzoyl-3-alkylthioureas by transamidation under microwave in dry media

Environmental Remediation by an Integrated Microwave/UV-Illumination Method. 1. Microwave-Assisted Degradation of Rhodamine-B Dye in Aqueous TiO2 Dispersions

“…Microwave radiation has found its place in several domestic, industrial, and medical applications. Interesting reports have appeared on the application of microwave radiation in such technologies as (1) organic syntheses, polymerization ( , ) and dehydration ( − ) processes; (2) inorganic syntheses by ceramic calcination and solidification ( , ); (3) environmental waste treatment (); (4) safety and biological aspects ( − ); (5) analyses and extraction ( − ); and (6) food sterilization (). The microwave technique may also be useful in decomposing nondegradable materials from wastes.…”

Thiourea and Selenourea and Their Applications

“…Reaction with amine leads to transamidation, whereas reaction with carboxylic acid gave acyl products (Scheme 16) [34,35].…”

Silica Gel-Mediated Amide Bond Formation: An Environmentally Benign Method for Liquid-Phase Synthesis and Cytotoxic Activities of Amides

“…Besides, this microwave-mediated method provided amides in only 10−25% yields when secondary amines were used. Because solid medium, such as silica gel, had been used previously as a solid support for acylthiourea formation under solvent-free microwave condition, we decided to try pyrolazation that was mediated by silica gel in solution phase, aiming to develop a new method for the synthesis of amides (Table ). By screening of solvents, we found that toluene was a good solvent for amide formation.…”
