标题:Synthesis of macrocyclic tetraamido-N ligands
发明人：GORDON-WYLIE SCOTT W; COLLINS TERRENCE J
权利人:UNIV CARNEGIE MELLON
摘要:New synthetic methods for the preparation of macrocyclic amido-N donor ligands are provided. The primary method of the present invention involves in general only two synthetic steps. In the first step, an α or β amino carboxylic acid is allowed to react with an optimal (approximately stoichiometric) amount of an activated malonate or oxalate derivative with mild heating. Upon completion of the double coupling reaction, hydrolysis of the reaction mixture yields a diamide containing intermediate (a macro linker). In the second step, stoichiometric amounts of a diamine, preferably an orthophenylene diamine, are added to the macro linker intermediate in the presence of a coupling agent and heat. This second double coupling reaction, is allowed to proceed for a period of time sufficient to produce a macrocyclic tetraamido compound. The substituent groups on the α or β amino carboxylic acid, the malonate, and the aryl diamine may all be selectively varied so that the resulting tetraamido macrocycle can be tailored to specific desired end uses. The macrocyclic tetraamide ligand may then be complexed with a metal, such as a transition metal, and preferably the middle and later transition metals, to form a robust chelate complex suitable for catalyzing oxidation reactions.

摘要:Novel group 6 organometallic compounds, supported on anions by means of at least one covalent metal-oxygen bond, are obtained by reaction of at least one borate or aluminate comprising at least one hydroxy group with at least one compound of a group 6 transition metal. These compounds are used in a catalytic composition utilized in an olefin metathesis method.

标 题 :Selective extraction of anions from solution
发明人：MEZEI GELLERT
权利人:WESTERN MICHIGAN UNIV RESEARCH FOUNDATION; THE BOARD OF TRUSTEES OF WESTERN MICHIGAN UNIV
摘要:A method of selectively extracting anions from an aqueous solution using an anion encapsulating aggregate formed upon the addition of a solvent, a copper contributor, a hydroxide contributor, a counterion contributor, and pyrazole to an aqueous solution containing the anions, or upon the addition of a solvent, a polymeric chain of [Cu II (μ-OH)(μ-pz)] ∞ and a counterion contributor to the aqueous solution. The aggregates include compounds of the formula cis Cu II x (OR 1 ) y (R 2 pz) z , where R 1 is H or an alkyl group, R 2 is H, or an alkyl group or a charged group, pz is pyrazolate and each of x, y, and z is an integer between about 1 and about 40. In addition, ligand-containing anion encapsulating aggregates can be formed by synthesis with a lig-and-bound pyrazole or by substituting the ligand-bound pyrazole for the pyrazole incorporated in the aggregate.

摘要:A method of selectively extracting anions from an aqueous solution using an anion encapsulating aggregate formed upon the addition of a solvent, a copper contributor, a hydroxide contributor, an optional counterion contributor, and at least one encapsulating anion to an aqueous solution containing the anions, or upon the addition of a solvent, a polymeric chain of [CuII(μ-OH)(μ-ea)]∞ and optionally, a counterion contributor to the aqueous solution. The aggregates include compounds of the formula cis-CuIIx(OR1)y(R2ea)z, where R1 is H or an alkyl group, R2 is H, or an alkyl group or a charged group, ea is an encapsulating anion, and each of x, y, and z is equal to an integer between about 1 and 40, inclusive. In addition, anion encapsulating aggregates can be formed by synthesis with alternate encapsulating anions by substituting alternate encapsulating anions for the encapsulating anion incorporated in the aggregate.
