About this app

Want to refresh your memory on named chemical reactions before an exam or a group meeting? The free ReactionFlash(R) app is a great way to learn Named Reactions, understand their mechanisms and view examples published in peer-reviewed literature or patents.

Designed and developed in consultation with Professor Dr. Erick M. Carreira of ETH Zürich, the app now covers over 1'266 named chemistry reactions. Professor Carreira has helped ensure that we have all the fundamental reactions that should be part of every chemist’s toolkit: from the best-known ones to the ones only Nobel Prize winners remember!

The app is designed like a set of flash cards so it can be used as a learning tool as well as a reference. Each ‘card’ shows the reaction, its mechanism and examples from peer-reviewed, published literature. It also has a quiz mode that lets you test your knowledge.

Linking into Reaxys enables you to find the most recent examples of each reaction, many with experimental details. Reaxys delivers experimental facts from the literature, enabling researchers to find the best synthetic routes and conditions. Find out more at https://www.elsevier.com/solutions/reaxys

Download the app now and see if you know all the named reactions!

Summary:
- Learn named reactions
- Review and understand mechanisms
- Explore examples published in peer-reviewed literature
- Take the ReactionFlash quiz and see how much you know

Dear Mohd Zahid, Thanks so much for your wonderful rating and valuable feedback. We’re thrilled that our app is useful to you. We’ll keep your suggestion for a tool with physical chemistry formulas in mind, but it is not something we will be implementing in the near future. Thanks again! Kind regards, The ReactionFlash team
