چکیده
The 6-amino-6-methyl-1,4-diazepine framework is a readily available neutral 6-electron ligand moiety, suitable to support cationic group 3 metal alkyl catalysts; it also provides convenient access to tri- and tetradentate monoanionic ligand derivatives.

Cationic scandium methyl complexes supported by a beta-diketiminato ("Nacnac") ligand framework.
The base-free dimethyl scandium complex supported by the bulky beta-diketiminato ligand ArNC((t)Bu)CHC((t)Bu)NAr (Ar = 2,6-(i)Pr(2)C(6)H(3), 1) reacts with various equivalencies of the strong organometallic Lewis acid B(C(6)F(5))(3) to give scandium alkyl cations. With 0.5 equiv, a monocationic mu-methyl dimer (2) was observed spectroscopically. Reaction with a further 0.5 equiv of borane gives...
متن کاملConformational analysis and synthetic approaches to polydentate perhydro-diazepine ligands for the complexation of gallium(III).
Synthetic approaches are reported to polydentate ligands based on 6-phenyl-6-amino-perhydro-1,4-diazepine. The synthetic route devised averts ring-opening reactions, allowing the exocyclic N-substituent to be introduced separately and involves a nitro-Mannich condensation, prior to chemoselective RANEY® nickel reduction. Comparison of the solid-state structures of four synthetic intermediates r...

The title neutral copper complex, [Cu(2)Cl(4)(C(8)H(17)N(3)O(2))(2)], shows a binuclear center with a Cu-(μ-Cl)(2)-Cu core, in which each copper ion is coordinated by the N,N,O donor atoms of the tridentate ligand 1,4,6-trimethyl-6-nitro-1,4-diazepine (meaaz-NO(2)) and three chloride exogenous ligands. Each metal ion is facially coordinated by meaaz-NO(2) through N,N,O donor atoms, whereas two ...

Cellulose was applied as a reusable and green catalyst for the facile four-component synthesis of 6-amino-4-aryl-3-methyl-1,4-dihydropyrano[2,3-c]pyrazole-5-carbonitrile derivatives using hydrazine monohydrate, ethyl acetoacetate, malononitrile and aryl aldehydes, under solvent-free and thermal conditions. The use of non-toxic and inexpensive catalyst, short reaction time, clean w...
متن کاملNeutral and cationic aluminium complexes containing a chiral (OSSO)-type bis(phenolato) ligand: synthesis, structures and polymerization activity.
Reaction of trimethylaluminium with the linked bis(phenol) trans-1,4-dithiocyclohexanediyl-2,2-bis(4,6-di-tert-butylphenol) (cydtbpH2, 1a) led to the chiral methyl aluminium complex [Al(cydtbp)Me] (2a) as both racemate and resolved enantiomers, which were characterized by multinuclear NMR spectroscopy and elemental analysis. Rac-{trans-1,2-dithiocyclohexanediyl-2,2-bis(6-tert-butyl-4-methylphen...
