Quick Method Found for Synthesis of Organic Compounds with Less Pollution
Tehran, Iran | Posted on September 25th, 2014 The proposed method increases the rate but decreases the pollution caused by the synthesis process.
Some organic compounds, including aryl ethynyl attached to triarylamine are used in electrophotography and light emission devices, including organic solar cells, due to their unique characteristics. In addition, they can be important parts of polymeric and natural materials. However, common methods for the production of these compounds face problems like long period or low production yield at normal operation conditions.
Zeinab Akbarzadeh, one of the researchers, explained about the new method, and said, "Arylethynyl compounds attached to triarylamine are usually synthesized by using palladium or copper containing catalysts. These compounds are produced with very low yield by using bulk catalysts. Therefore and taking into account the importance of these compounds in various industries, we sought to synthesize them at shorter time with high efficiency."
The effects of solvent, type and percentage of catalyst on the efficiency of the reaction have been studied in this research. Results showed that solvent-free reactions with nanostructured catalysts have higher efficiency, to the extent that in the presence of only 2% of iodide copper, the efficiency reaches 78%. In case non-nanometric catalysts are used in this reaction, the efficiency of the reaction does not reach higher than 56% even by using 12% of catalyst.
Results of the research have been published in Ultrasonics Sonochemistry, vol. 22, January 2015, issue, pp. 365-370.
