The U3+ allyl complexes (C5Me5) 2U[CH2C(R)CH2] (R = H, Me) display three different types of reactivity, as exemplified by reactions with PhNi - NPh, cyclooctatetraene, and CO2. Two equivalents of (C 5Me5)2U[CH2C(R)CH2] effect a four-electron reduction of PhNi - NPh to form the bis(imido) complex (C5Me5)2U(i - NPh)2 and the bis(allyl) species (C5Me 5)2U[CH2C(R)CH2]2. Two-electron reduction of C8H8 occurs to form (C 5Me5)(C8H8)U[CH2C(R) CH2] products that contain only one cyclopentadienyl ring per metal. With CO2 at 80 psi, both reduction and insertion occur. A hexametallic uranium carbonate, [(C5Me5) 2U]6(μ-κ1:κ2-CO 3)6, is isolated as well as the bis(carboxylate) complexes (C5Me5)2U[κ2-O,O′- O2CCH2C(R)i - CH2]2. The polymetallic carbonate complex can also be synthesized from [(C 5Me5)2U]2(μ-η6: η6-C6H6) and [(C5Me 5)2U][(μ-Ph)2BPh2] and CO 2.
