Getting Started With The Platform ReactionFlash

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

This app is great for students, especially for the ones preparing for competitive exams. But few can be made, such as including the temperature range of the reaction, mentioning where the substitution or addition or elimination takes place in less or more hindered sites, will it be cis or trans, the yield percentage range, etc.

This is an excellent app for students of all grades who are in some way linked to organic chemistry. The layout and user interface is at its simplest best. App has loads of information and the reaction mechanisms are so elaborately explained. I have been using this app foe around a year now and its utility never ceases to awe me. Hats off to the developer team. 🤗🤗🤗🤗👍👍👍👍

really frickin good app my only reserve is the quizzing mode where it just gives a name. i think itd be cool to be able to see just a start and end compound or maybe where they give either reagent, main compound, or endpoint and give options. But really good as i can review any reaction happily
