Zur Loeslichkeitsbeeinflussung von Kohlenwasserstoffen in Wasser. III. Der Einfluss von Harnstoff, p-Toluensulfonsaeure und Triethylbenzylammoniumbromid

The present work reports solubility data of toluene, chlorobenzene and nitrobenzene in pure water and aqueous solutions of urea, p-toluenesulfonic acid and triethylbenzylammoniumbromide at 25 deg C and 40 deg C for nitrobenzene also at 60 deg C.Addition of hydrotropic agents increases the solubility of all investigated solutes.Thermodynamic functions were calculated from solubilities.Interactions between solute, water and hydrotrope are discussed.

Mechanism and kinetics of Horner-Wadsworth-Emmons reaction in liquid-liquid phase-transfer catalytic system

Liquid-liquid phase-transfer catalytic (LL-PTC) system suitable for symmetric distyryl compounds could not be used to synthesize asymmetric derivates. Relatively low value, the time-dependence of the interfacial tension with only phosphonate in the organic phase and high background reaction rate demonstrated that “weakly acidic” phosphonate was adsorbed on the interfacial layer and deprotonated by excess “naked” OH- without the help of the catalyst. Phase-transfer catalyst participated in the transfer process of the carbanion and accelerated the bond-forming reaction. However, the distributing region for the carbanion ion-pair in this PTC system was dependent on the usage of the catalyst and the mechanism would change from the interfacial mechanism to the extraction mechanism. Accordingly, the mechanism including adsorption, deprotonation, ion-exchange reaction, distribution and bond-forming reaction was proposed, and the kinetic model was performed. The activation energy and the dependence of catalytic activity on lipophilicity and accessibility parameter also supported the proposed mechanism. The rate-determining step was not the bond-forming reaction for each mechanism and the apparent reaction rate was relevant to the generation rate of the carbanion and the ion-exchange reaction rate.

ATP3 and MTP3: Easily Prepared Stable Perruthenate Salts for Oxidation Applications in Synthesis

The Ley?Griffith tetra-n-propylammonium perruthenate (TPAP) catalyst has been widely deployed by the synthesis community, mainly for the oxidation of alcohols to aldehydes and ketones, but also for a variety of other synthetic transformations (e.g. diol cleavage, isomerizations, imine formation and heterocyclic synthesis). Such popularity has been forged on broad reaction scope, functional group tolerance, mild conditions, and commercial catalyst supply. However, the mild instability of TPAP creates preparation, storage, and reaction reproducibility issues, due to unpreventable slow decomposition. In search of attributes conducive to catalyst longevity an extensive range of novel perruthenate salts were prepared. Subsequent evaluation unearthed a set of readily synthesized, bench stable, phosphonium perruthenates (ATP3 and MTP3) that mirror the reactivity of TPAP, but avoid storage decomposition issues.
