The second-order kinetics of iodination of imidazole and 2-methylimidazole in aqueous medium at various pH values and temperatures are studied in the presence and absence of a base catalyst. The reactions being electrophilic substitutions, molecular iodine is the sole iodinating agent, as the react...
(Received March 24, 1972) ABSTRACT: The catalytic hydrolysis of 3-nitro-4-acetoxy-benzoic acid was carried out mainly at 30°C, pH 8.0 in 1.0-M aqueous KCI. The polymer catalysts used were prepared by partial quaternization of the homopolymer and copolymers of 1-vinyl-2- methylimidazole ...
Reactions with RuCl3., and [Ru(Ph3E)2Cl3(MeOH)] yield [RuClL2] and [Ru(Ph3E) 2L3] (E = P or As; L = imidazolate, Iz or 2-methylimidazolate, Melz) respectively, whereas [Ru(Ph3P)3Cl2] affords [Ru(Ph3P)2L2]. The stoichiometry of the compounds is consistent with the ...
The reaction system NiCl2/Na2edt/S22- (edt2- = 1,2-ethanedithiolate) in a 4:4:1 ratio in methanol affords the [Ni4(S2)(edt)4]2- anion (1), which was isolated as its Ph4P+ salt. [Ph4P]2[Ni4(S2)(edt) 4]·MeOH (2) crystallizes in the tricli... W Tremel,G Henkel -...
