n the last two decades, the search for sustainability in chemical reactions has attached a lot of attention. In this focus review, the use of ultrasound (US) as an alternative energy source in organic synthesis is presented. The improvement of the performance of chemical reactions due to the cavitation effect has been previously studied and described. The use of US guarantees often higher yields than other green methodologies, as microwave or ball milling. The impressive positive effect of US in organic synthesis are demonstrated in this review mainly in organometallic and multi‐component reactions (MCRs), aimed to prepare bioactive compounds. A particular attention is dedicated to the US‐assisted synthesis of valuable organochalcogen compounds with pharmacological activity.

Abstract

In this focus review, the use of ultrasound (US) as an alternative energy source in organic synthesis is presented. The improvement of the performance of chemical reactions due to the cavitation effect has been previously studied and described. The use of US guarantees often higher yields than other green methodologies, as microwave or ball milling. The impressive positive effect of US in organic synthesis are demonstrated in this review mainly in organometallic and multi‐component reactions (MCRs), aimed to prepare bioactive compounds.
