Effect of ionic force on the kinetics of some substitution reactions in aqueous solutions

Effect of ionic force on the kinetics of some substitution reactions in aqueous solutions. Plakhotnik, V. N.; Drabkina, A. Kh. (Dnepropetr. Inst. Inzh. Zheleznodorozhn. Transp. im. Kalinina, Dnepropetrovsk, USSR). Kinet. Katal., 18(1), 227-31 (Russian) 1977. 17084-08-1 and 16057-15-1 are cas registry numbers of chemicals which are used as reagents here. CODEN: KNKTA4. DOCUMENT TYPE: Journal CA Section: 67 (Catalysis and Reaction Kinetics) Section cross-reference(s): 78 The effect of ionic strength (.mu. = 0-10.0) was studied during hydrolysis and aquation of a series of acido complexes (BF4-, SiF62-, B(OAc)4-, GeF62-, SO3F-, S2O72-, S2O62-). A salt effect was obsd. on the entropy of activation of reactions occurring by a dissoc. mechanism. The use of salt effects to interpret aquation mechanism is discussed. .

Reactivity of hexafluoro complexes of Group IVA elements

Reactivity of hexafluoro complexes of Group IVA elements. Plakhotnik, V.Some chemicals with cas registry numbers like 18588-21-1 and 17084-08-1 are also used. N.; Yaryshkina, L. A.; Rossikhin, V. V. (Dnepropetr. Inst. Inzh. Transp., Dnepropetrovsk, USSR). Teor. Eksp. Khim., 27(4), 491-3 (Russian) 1991. CODEN: TEKHA4. ISSN: 0497-2627. DOCUMENT TYPE: Journal CA Section: 67 (Catalysis, Reaction Kinetics, and Inorganic Reaction Mechanisms) Section cross-reference(s): 65, 78 The electronic and geometric structures were calcd. for Group IVA (M = Si, Ge, Sn) MF62- complexes and their aqua derivs. by using a SCF MO LCAO method. The results of these calcns. indicate that these complexes can undergo substitution by an associative mechanism. Exptl. kinetic data for the alk. hydrolysis of SnF62- at 276-303K support an associative mechanism. .
