Synthesis and structure of sulfonamido cyclopentadiene titanium complexes: X-ray structure of Ti(η5:σ-C5H4CH2CH2NSO2C6H4CH3)Cl2
摘要:
The reaction of Ti(NMe(2))(4) with the bidentate ligand C(5)H(4)CH(2)CH(2)NHSO(2)C(6)H(4)CH(4) yields the titanium sulfonamido cyclopentadiene complex Ti(eta(5) : sigma-C(5)H(4)CH(2)CH(2)NSO(2)C(6)H(4)CH(3))(NMe(2))(2). This compound reacts with two equivalents Me(3)SiCl to give the novel dichloride complex Ti(eta(5) : sigma-C(5)H(4)CH(2)CH(2)NSO(2)C(6)H(4)CH(3))Cl(2) whose molecular structure was determined by single crystal X-ray crystallography.

Synthesis of chiral N-alkyl-cyclopentadienyl sulfonamides
摘要:
The reaction of sodium cyclopentadiene or lithium indene with tosylamino tosylates of amino alcohols yield a series of novel N-alkylcyclopentadiene sulfonamides. These cyclopentadiene derivatives are potential ligands capable of chelating to transition metals. Optically active derivatives were prepared starting from chiral beta-amino alcohols.
