General Description

Potassium 2,4-dichlorophenolate is a chemical compound derived from phenol and chlorine, in which one hydrogen atom has been replaced by a potassium atom. It is commonly used as a fungicide and bactericide in agricultural and horticultural applications, where it is employed to control a range of fungi and bacteria that can harm crops. The compound works by disrupting the cellular membranes of the microorganisms, leading to their death. Additionally, potassium 2,4-dichlorophenolate is also utilized as a preservative in various industrial products and formulations, due to its ability to inhibit the growth of microorganisms. However, it is important to use this compound in accordance with proper safety protocols and regulations, as it can be toxic if ingested or inhaled in large amounts. Overall, potassium 2,4-dichlorophenolate plays a valuable role in the protection of plants and products from microbial damage.

A kinetic study on nucleophilic displacement reactions of aryl benzenesulfonates with potassium ethoxide: Role of K+ ion and reaction mechanism deduced from analyses of LFERs and activation parameters

Pseudofirst-order rate constants (kobsd) have been measured spectrophotometrically for the nucleophilic substitution reactions of 2,4-dinitrophenyl X-substituted benzenesulfonates 4a-f and Y-substituted phenyl benzenesulfonates 5a-k with EtOK in anhydrous ethanol. Dissection of k obsd into kEtO- and kEtOK (i.e., the second-order rate constants for the reactions with the dissociated EtO - and ion-paired EtOK, respectively) shows that the ion-paired EtOK is more reactive than the dissociated EtO-, indicating that K + ion catalyzes the reaction. The catalytic effect exerted by K + ion (e.g., the kEtOK/kEtO- ratio) decreases linearly as the substituent X in the benzenesulfonyl moiety changes from an electron-donating group (EDG) to an electron-withdrawing group (EWG), but it is independent of the electronic nature of the substituent Y in the leaving group. The reactions have been concluded to proceed through a concerted mechanism from analyses of the kinetic data through linear free energy relationships (e.g., the Bronsted-type, Hammett, and Yukawa-Tsuno plots). K+ ion catalyzes the reactions by increasing the electrophilicity of the reaction center through a cyclic transition state (TS) rather than by increasing the nucleofugality of the leaving group. Activation parameters (e.g., ΔH? and ΔS?) determined from the reactions performed at five different temperatures further support the proposed mechanism and TS structures.
