The chapter aims to illustrate the advantages of ion-radical organic chemistry with respect to syntheses of desirable products. It focuses on typical synthetic approaches. The examples provided follow these guidelines:

1. The procedures given must have de nite (and tangible) advantages 2. Yields of the products aimed must be high enough 3. The products themselves must be of practical interest 4. The synthetic procedures included sometimes are the only ones available for a certain


At this point, the author would not like to dishearten the readers who are interested in the mechanistic aspect of this book. For them, such a truism can be offered-a chemist’s heart is devoted to mechanisms, but public demands for the chemist originated due to the need for new substances and reactions. Necessity is the mother of inventions! Therefore, the chapter puts forth the general ideology of pursuits in the area of ion-radical organic chemistry and examines the methodologies that have evolved in the search for solutions to synthetic problems. This chapter details achievements of ion-radical organic syntheses, not only for their scienti c and practical merits, but also for the aesthetic appeal of the examples chosen and the effective solutions that have emerged.
