1,2-Dibenzoyl- and 1-benzoyl-2-acetylhydrazines as reagents for recovering Cu(II) ions from alkaline solutions
Radushev,Chekanova,El'chishcheva,Ershova
, p. 368 - 371 (2007)
The conditions of complexation of 1,2-diacylhydrazines (H2L) C6H5C(O)NHNHC(O)R, where R = C6H5 or CH3, with Cu(II) ions in alkaline solutions were studied. The composition of the complexes formed by precipitation of Cu(II) from alkaline solutions, (CuOH)2L and CuL, was determined. The possibility of afterpurification of solutions with a low Cu(II) content by pneumatic flotation using H2L was examined.

In formula (1), X represents a nitrogen atom or a group represented by ═C(RX)—; R1 represents an alkyl group having 4 or more carbon atoms; R2 represents an alkyl, cycloalkyl, alkoxy, cycloalkoxy, aryl, aryloxy, monovalent heterocyclic, or substituted amino group or a halogen atom; rings A and B each independently represent an aromatic hydrocarbon ring or an aromatic heterocyclic ring; M represents a rhodium, palladium, iridium, or platinum atom; n1 represents an integer of 1 or more, n2 represents an integer of 0 or more, and n1+n2 is 2 or 3; A1-G1-A2 represents an anionic bidentate ligand; A1 and A2 each independently represent a carbon atom, an oxygen atom, or a nitrogen atom; and G1 represents a single bond or an atomic group constituting a bidentate ligand together with A1 and A2.
Synthesis of 1,3,4-oxadiazoles from 1,2-diacylhydrazines using [Et 2NSF2]BF4 as a practical cyclodehydration agent

supporting information; experimental part, p. 988 - 993 (2012/04/10)
The preparation of 1,3,4-oxadiazoles from 1,2-diacylhydrazines using XtalFluor-E ([Et2NSF2]BF4) as cyclodehydration reagent is described. Various functionalized 1,3,4-oxadiazoles were synthesized and it was found that the use of acetic acid as an additive generally improved the yields.
