The reactivity of some 1,2-alkadienephosphonates towards phenyltelluryl halides was investigated. A plausible mechanism of the reaction is discussed. Consequently, many attempts for their synthesis have been made. One of the easiest and most fruitful methods for the synthesis of these derivatives is electrophile-induced heterocyclization of 1,2-alkadienephosphonates.

Chapter 17 - Reactions of aromatic compounds. In this chapter, we will study several of these reactions and then consider how substituents on the ring influence its reactivity toward electrophilic aromatic substitution and the regiochemistry seen in the products. We will also study other reactions of aromatic compounds, including nucleophilic aromatic substitution, addition reactions, reactions of side chains, and special reactions of phenols.

Chapter 8 - Reactions of Alkenes. This chapter include objectives: Explain why electrophilic additions are among the most common reactions of alkenes; Predict the products of the reactions of alkenes, including the orientation of the reaction (regiochemistry) and the stereochemistry; propose mechanisms to explain the observed products of alkene reactions; use retrosynthetic analysis to solve multistep synthesis problems with alkenes as reagents, intermediates, or products.

The formation of carbon–carbon single bonds is of fundamental importance in organic synthesis. As a result, there is an ever-growing number of methods available for carbon–carbon bond formation. Many of the most useful procedures involve the addition of organometallic species or enolates to electrophiles, as in the Grignard reaction, the aldol reaction, the Michael reaction, alkylation reactions and coupling reactions. Significant advances in both main-group and transition-metal-mediated carbon–carbon bond-forming reactions have been made over the past decade.
