Ask Reaxys is a kind of Google search bar:
For example, if you want to find the boiling point of benzaldehyde, you type in ‘boiling point benzaldehyde’ and get a list of references in which the boiling point is given. Please note, you must enter the search query in English. You can use this to search for reactions. You enter the reaction in the structure editor (to change this go to the Settings tab). You can enter a complete reaction or just a single compound. The results can be filtered in various ways.
