OXIDATIVE REACTION OF 1,5-DITHIONIABICYCLO[3.3.0]OCTANE BIS(TRIFLUOROMETHANESULFONATE) WITH DIENE COMPLEXES OF ZIRCONIUM AND TANTALUM - SYNTHESIS OF CP2ZR(OTF)(2)(THF) AND CP(ETA(4)-1,3-BUTADIENE)TA(OTF)(2)

摘要

Oxidative addition of a hypervalent organosulfur compound, 1,5-dithioniabicyclo[3.3.0]octane bis(trifluoromethanesulfonate) (1), to diene complexes of zirconium and tantalum, Cp2Zr(eta(4)-1,3-butadiene) and CpTa(eta(4)-1,3-butadiene)(2), in THF resulted in the almost quantitative formation of bis(triflate) complexes of zirconium, Cp2Zr(OTf)(2)(thf) (3), and tantalum, CpTa(eta(4)-1,3-butadiene)(OTf)(2) (5), respectively.
