The aim of this part of the book is to look at current practical applications of organic ion-radical chemistry. Chapter 8 examines patents and original (experimental) papers that offer commercial advantages compared with conventional approaches. It pays special attention to newly developed branches of material science that may become technically important in the near future. Ion-radical organic chemistry opens new possibilities in the synthesis of material for molecular electronic applications, including problems connecting with microelectronic core materials, organic metals, and magnets. A special section of the chapter is devoted to study the mechanism of lubrication during the rubbing of metallic surfaces. The other one considers ion-radical reactions taking place in industrial cooking of woods and fuel desulfurization. It is dif cult to overestimate technical importance of all these problems.
