Chemical Synthesis and Characterization

Addition of Me3SiI to UO2(Aracnac)2 (ArNC(Ph)CHC(Ph)O, Ar = 3,5-tBu2C6H3) (1) results in the formation of U(OSiMe3)2I2(Aracnac) (2) in moderate yield. Also formed in the reaction are I2 and ArNC(Ph)═CHC(Ph)OSiMe3, the product of [Aracnac]− abstraction by Me3Si+. In contrast, reaction of 1 with Me3SiX (X = Cl, OTf) only results in the formation of UO2(OTf)2(AracnacH)2(Et2O) (3) and UO2Cl2(AracnacH)2 (4), respectively.
