Series of polynuclear diorganotin(IV) complexes with di-halogenbenzohydroxamate ligands (substituents=2,4-Cl(2), 2,4-F(2), 3,4-F(2), 2,5-F(2), 2,6-F(2)), formulated as the polymeric [R(2)SnL](n)a (1:1) and the tetranuclear [R(4)Sn(2)(HL)(2)(L)](2)b (2:3) (HL=arylhydroxamate), were prepared and characterized by FT-IR, (1)H, (13)C, (119)Sn NMR spectroscopies, elemental analyses and melting point ...
متن کاملSynthesis and structures of (R)-cyclopentadienyl-binaphthoxy titanium(IV) complexes and catalytic properties for olefin polymerization.
Two new chiral pre-ligands, (R)-3,3'-bis(tetramethylcyclopentadienyl)-2,2'-bismethoxy-1,1'-bisnaphthalene (1) and (R)-3-tetramethylcyclopentadienyl-2,2'-bismethoxy-1,1'-bisnaphthalene (2), were synthesized by reaction of (R)-3,3'-dilithium-2,2'-bismethoxy-1,1'-bisnaphthalene with 2,3,4,5-tetramethyl-2-cyclopentenone at room temperature. Treatment of the pre-ligands 1 and 2 with butyllithium and...
