Special Issue Information

Dear Colleagues,

Determining the most probable reaction mechanism means assuming and determining the most efficient step-by-step path by which a chemical compound is transformed into another chemical compound. Detailed knowledge of the reaction mechanisms allows us to predict the reaction course and the final outcome of the reaction, as well as to manage the reaction process. The fact that there is an impetus to discover the most probable reaction path means that it is possible that the reaction follows more than one reaction pathway. During the chemical transformation, the compound can gradually change to its final form, passing through a series of transitional states and intermediate species, whose existence, structure and stability are often not easily determined and proven. Even a small change in the reaction conditions can lead to a change in the dominant reaction pathway, or it can completely change the course of the reaction. All this makes finding the operative mechanism of a chemical reaction a kind of challenge despite the approach that is taken to determine it; whether on the basis of kinetic or thermodynamic parameters, or whether the reaction pathway is determined from a theoretical or from an experimental aspect.

Studies have shown that the incorporation of fluorine into materials can improve their properties, but C–F bonds are not readily formed in nature. Although some researchers have studied the reaction of fluorinating alkenes catalyzed by hypervalent iodine, far too little attention has been paid to its reaction mechanism. This study aimed to explore the mechanism of the hypervalent iodine-catalyzed 1,4-difluorination of dienes. We found that the catalyst is favorable for the activation of C1=C2 double bonds through halogen bonds, and then two HFs interact with one F atom in the catalyst via hydrogen bonds, resulting in the cleavage of I–F bonds and the formation of [F–H∙∙∙F]. Subsequently, the catalyst interacts with C1, and the roaming [F–H···F] attacks C4 from the opposite side of the catalyst. After the fluorination step is completed, the nucleophile F substitutes the catalyst via the SN2 mechanism. Our calculations demonstrated that the interaction between HF and F is favorable for the stabilization of the transition state within the fluorination process for which the presence of two HFs in the reaction is the best. We also observed that [F–H∙∙∙F] attacking C4 from the opposite side of the catalyst is more advantageous than attacking from the same side. This study therefore offers a novel perspective on the mechanism of the hypervalent iodine-catalyzed fluoridation of dienes. Full article
