In this video, Louise Summerton at the Green Chemistry Centre of Excellence, University of York describes commonly used efficiency based metrics, typically based on mass inputs/outputs, that can be readily calculated and interpreted to give an indication of the greenness of a reaction.
Direct amidation exercise (part 1)
Here is an an example reaction (Scheme 1) and a series of questions (see below) to provide you with some practice of calculating efficiency based metrics. You will find the information you need to make these calculations in the accompanying data sheet.
After completing the exercise, you can check your answers against the answer sheet.
