Sommario/riassunto

In recent years silicon-centered radicals have played an important role in organic synthesis, polymer chemistry and material sciences. The aim of this book is to offer for the first time a description of silyl radicals within an interdisciplinary context, connecting structural characteristics and chemical properties to their application in different areas of chemistry. The first time different aspects of silyl radicals have been brought togetherExcellent reference tool for experienced practitioners of radical and/or silicon chemistryPresents various aspects of the
