The synthesis of oxidorhenium(V) complexes with tridentate and potentially tetradentate ligands of the type [ReOX2(L)] {X = Cl or Br; L = 2-[CH2N(Me)CH2CH2OCH3]-4,6-di-tBu- phenolate, 2-[CH2N(Me)CH2CH2SCH 2CH3]-4,6-di-tBu-phenolate, 2-[CH2N(Me)CH 2CH2N(CH3)2]-4,6-di-tBu-phenolate, 2-[CH2N(Me)CH2CH2N(CH2CH 3)2]-4,6-di-tBu-phenolate, 2-[CH2N(CH 2CH2OCH3)2]-4,6-di-tBu-phenolate,2- [CH2N(CH2CH2SCH2CH3) 2]-4,6-di-tBu-phenolate, 2-[CH2N{CH2CH 2N(CH2CH3)2}2]-4,6-di- tBu-phenolate} 1-14 is reported. All complexes were spectroscopically characterized and shown to be isomerically pure. Compounds 1, 2, 9, and 11 were crystallographically characterized and show similar octahedral geometries with trans O=Re-O and cis O=Re-Cl bonds. All synthesized complexes 1-14 are catalyst precursors for the epoxidation of cyclooctene with tert-butyl hydrogenperoxide (TBHP). Yields of the formed epoxide were up to 55a% with all precursors. Oxidorhenium(V) complexes of the type [ReOX2L] (X = Cl, Br) that contain tridentate and tetradentate phenolate-based ligands were prepared and tested for their catalytic activity in epoxidation reactions.
