Abstract
The stilbene complex of ytterbium (PhCH=CHPh)Yb(THF)(2) (1) was prepared by the reaction of YbI2(THF)(2) with a twofold excess of (PhCH=CHPh)(-.) Li+. Based on the data of IR and ESR spectroscopy and on the results of magneti c measurements, compound 1 was characterized as a complex of divalent ytter bium with the stilbene dianion. The reactivity of complex 1 toward differen t types of reagents was studied. The structure of the product of the reacti on of 1 with 2,4,6-tri(tert-butyl)phenol (2,4,6-(Bu3C6H2O)-C-t)(2)Yb(THF)(3 ) was established by X-ray diffraction analysis.
