As in my previous book ("Advanced Organic Chemistry"), the focus is on reactions of organic compounds. The major successes that were achieved thanks to the application of high-quality electron theory in Oranic chemistry are reflected. The book consists of three parts. The first, devoted to reactions, usually called ionic, includes, as is customary, two sections, respectively, the reagent is considered electrophilic or nucleophilic. In the second part, radical reactions are described, and in the last - molecular. Most reactions for which the mechanism is not convincingly proven are naturally classified only conditionally.
