Most important organic molecules contain more than one functional group, and very often the interaction between these groups determines the chemical and biological behaviour of the compounds. This concise text outlines some of the methods used to prepare bifunctional compounds and then surveys the chemistry of some of the more important classes. Problems - with solutions - and suggestions for further reading are provided, and students who are familiar with the reactions of monofunctional compounds will find this text an invaluable introduction to the more advanced aspects of organic chemistry.
