Název v původním jazyce

Zinc complexes chelated by bifunctional ketiminate ligands: Structure, reactivity and possible applications in initiation of ROP and copolymerization of epoxides with carbon dioxide

Popis výsledku v původním jazyce

Bifunctional ketiminate zinc complexes were synthesized via alkyl or LiCl elimination route from appropriate zinc species (ZnCl2 or ZnEt2) and methoxyaryl substituted monoanionic ketimine {[2- or 3- or 4-(MeO)C6H4]}N(H)C(Me)=CHC(Me)=O. Homo- or heteroleptic complexes were prepared and characterized by the help of multinuclear NMR spectroscopy techniques. One of the heteroleptic ethyl substituted zinc complexes - {?2-N,O-[(2-MeO)C6H4Ndouble bond; length as m-dashC(Me)-CHdouble bond; length as m-dashC(Me)-O]ZnEt}2 was selected for further reactivity experiments with alcohols and amines. Molecular structures of some products were determined by X-Ray diffraction methods showing di- or trinuclear arrangement in solid state caused by the presence of intramolecular zinc-oxygen or zinc-nitrogen bridges. {?2-N,O-[(2-MeO)C6H4Ndouble bond; length as m-dashC(Me)-CHdouble bond; length as m-dashC(Me)-O]ZnEt}2 was also screened for of its catalytic activity in co/polymerization reactions (ROP: trimet
