Please supply reaction scheme images for your favorite reactions. I need some good examples to illustrate (using Reaxys) how a given functionality is converted into another functionality and which protocol I need to use so that a third functionality remains stable during the reaction (the use of free sites and generic groups etc). The examples shouldn't be too basic or too complex. I don't have access to a modern organic chemistry textbook.

@Bill, thanks for the question. You might get a better response by re-phrasing the question in terms that relate to experimental chemistry. It sounds like you're asking for some examples of reactions to use in your training, no? How about something like "What's your favorite preparative organic reaction?" In the body, you could ask for images of the reaction scheme. Just one idea. Don't worry, everything can be edited on this site, so feel free to give it a try. – Rich Apodaca Nov 18 at 18:31
@Bill, you should see an "edit" link under your question. Just click on it and you'll be able to change the title and body of your question as many times as you like. If for some reason you can't, feel free to use the 'feedback' link at the top of this screen, or here: feedback.chempedia.com – Rich Apodaca Nov 18 at 18:53

My vote would be direct reductive amination for the preparation of secondary and tertiary amines:

My favorite procedure is the one published by Abdel-Magid and coworkers using sodium triacetoxyborohydride at room temperature in halogenated solvents. It has broad functional group tolerance, works well on large and small scale, doesn't use anything particularly hazardous, accepts a large set of commercially-available inputs, and produces products that are highly relevant to drug discovery.
