This primer provides a much needed introduction to the organionitrogen chemistry. Nitrogen plays a key role in all areas of organic chemistry, from DNA and proteins through pharmaceuticals to man made drugs and new material. Despite this large coverage, there are just a handful of key principles which underpin the chemistry. This concise primer covers these principles discussing all of the main organonitrogen functional groups. It develops the themes logically under three specific sections, giving a clear overview of the synthesis, reactions and properties of organonitrogen compounds.
