Abstract:
The reaction of 1,1,3,3-tetramethylguanidine (HTMG) with [UO(2)Cl(2)(THF)2] yielded [UO(2)Cl(2)(HTMG)2] 1, the first uranyl tetralkylguanidine adduct reported, further investigation led to the synthesis of [UO(2)(DBP)2(HTMG)2] 2 and [UO(2)(DBP-4-Me)2(HTMG)2] 3 via the reaction of [UO(2){N(SiMe(3))2}2(THF)2] with HTMG and the appropriate aryl alcohol, HO-2,6-(t)Bu(2)-4-RC(6)H(2) (R = H, DBP; R = CH(3), DBP-4-Me).
