Ultrasound: A boon in the synthesis of organic compounds

Prebiotic Microreactors: A Synthesis of Purines and Dihydroxy Compounds in Aqueous Aerosol

“…This kind of ultrasonic device generates a continuous and stable bubble-aerosol-droplet cycle by capillary wave formation. The nebulizer does not generate cavitation bubbles in the bulk, the main mechanism for the sonochemical processes (Dalby et al 1997;Singh et al 1998).…”

Rate Enhancements Due to Ultrasound in Isoquinolinium Dichromate and Isoquinolinium Chlorochromate Catalyzed Chlorination of Aromatic Compounds in Presence of KHSO4/KCl

“…Cavitation induces very high local temperatures in the reaction mixture and enhances mass transfer [20][21][22][23][24][25][26][27][28][29].…”

“…We also wish to explore the use of ultrasound to assist IQCC and IQDC mediated chlorination reactions with a view to accelerate chemical reactions for achieving better yields as well as improving the greenery of reaction protocols. Earlier reviews and publications in this field [22][23][24][25][26][27][28][29][30][31][32] proved the importance of ultrasonically assisted organic synthesis and also highlighted that sonication using ultrasound is not only simple, but also satisfies both economical and environmental demands, as recommended by Anastas and Warner in the green chemistry formulations [33]. linium dichromate (IQDC) and isoquinolinium chlorochromate (IQCC) were prepared as reported method [20,21].…”

Ultrasound Promoted Green and Facile One‐Pot Multicomponent Synthesis of 3,4‐dihydropyrano[c]chromene Derivatives

“…On the other hand, ultrasound promoted reactions paved way for the modi�cation and improvement of several existing synthetic methodologies by enhancing their reaction rates [15,16] thus appending considerable value addition to the green chemistry procedures. e cavitation energy produced during the process of ultrasonication paves way for alternative pathways due to the formation of high energy intermediates thereby modifying and improving the reaction rates [17].…”
