| Abstract: | Homo- and heteroleptic aryloxides of the type MX4–x(OAr)x M = TiIV, ZrIV; X = OPri, Cl; x = 1,2,3,4; OAr = OC6H4Pri-4(OAr1), OC6H3Me-2-Pri-5(OAr2), OC6H3Me-5-Pri-2(OAr3), OC6H2Me3-2,4,6(OAr4), OC6H3But2-2,4(OAr5), OC6H3But2-2,6(OAr6)] have been prepared either by alkoxo–aryloxo or chloro-aryloxo exchange reactions in benzene or tetrahydrofuran. All these new derivatives have been characterized by elemental analyses, spectroscopic (i.r., 1H-, 13C-n.m.r.) studies and molecular weight measurements. The FAB mass spectral studies of four representative derivatives Support a dimeric nature for Ti(OC6H3Me-5-Pri-2)4], TiCl2(OC6H3Me-5-Pri-2)2], and Zr(OC6H3But2-2,4)4(thf)], whereas the derivative ZrCl(OC6H3But2-2,4)3(thf)] is monomeric. |
