Organocopper compounds are now an integral part of every modernsynthesis laboratory, allowing important stages of synthesis to becarried out in an elegant fashion. Yet a certain amount of experienceis needed if they are to be used effectively. Non-experts in thefield often have difficulty in choosing the most suitable reagent fora particular substrate and the prerequisites for the reaction. Thismanual, edited by Norbert Krause, answers such questions, since itcontains all the useful tips and tricks on organocopper compounds -information gained from personal experience by the international teamof authors. This allows those working in laboratories in bothacademia and industry to determine the optimal reagent for theirneeds using the substrates available for reaction and the desiredproducts. The result is a more effective use of these synthesis toolsin everyday laboratory practice.
