the molecular and electronic structures of dithio- and diselenophosphinate, (E2PR2)1– (E = S, Se; R = iPr, tBu), with thorium(IV) and uranium(IV) complexes. For the thorium dithiophosphinate complexes, reaction of ThCl4(DME)2 with 4 equiv of KS2PR2 (R = iPr, tBu) produced the homoleptic complexes, Th(S2PiPr2)4 (1S-Th-iPr) and Th(S2PtBu2)4 (2S-Th-tBu). The diselenophosphinate complexes were synthesized

The ketimide anion R2CN− is an important class of chemically robust ligand that binds strongly to metal ions and is considered ideal for supporting reactive metal fragments due to its inertspectator nature; this contrasts with R2N− amides that exhibit a wide range of reactivities. Here, we report the synthesis and characterization of a rare example of an actinide ketimidecomplex [Th(BIPMTMS)N(SiMe3)2}(NCPh2)]

and K2[Th(═NAr)2N″2], are readily made from insertion reactions (Ar = aryl, N″ = N(SiMe3)2) into the Th-C bond of the cyclometalated thorium amides [ThN″2(N(SiMe3)(SiMe2CH2))] and K[ThN″(N(SiMe3)(SiMe2CH2))2]. X-ray and computational structural analyses show a "transition-metal-like" cis-bis(imido) geometry and polarized Th═N bonds with twice the Wiberg bond order of the formally single Th-N bond in

Why do U react like that? Reaction of 2‐Li‐C6H4CH2NMe2 with [MCl4(DME)n] (M=Th, n=2; M=U, n=0) results in the formation of a thoriumarylcomplex, [Th(2‐C6H4CH2NMe2)4] or a uraniumbenzynecomplex, [Li][U(2,3‐C6H3CH2NMe2)(2‐C6H4CH2NMe2)3]. A DFT analysis suggests that the formation of a benzynecomplex with U but not with Th is a kinetic and not thermodynamic effect.
你为什么会这样反应?2 Li-C 6 H 4 CH 2 NMe 2与[MCl 4(DME)n ](M = Th,n = 2; M = U,n = 0)的反应导致a芳基络合物的形成, [Th(2-C 6 H 4 CH 2 NMe 2)4 ]或铀苯炔配合物[Li] [U(2,3-C 6 H 3 CH 2 NMe 2)(2-C 6 H 4 CH 2 NMe 2)3]。DFT分析表明,与U而不与Th形成的苯并配合物是动力学而非热力学效应。

tris[2-amido(2-pyridyl)ethyl]amine ligand, L, with thorium(IV) and uranium(IV). Using a salt-metathesis strategy from the potassium salt of this ligand, K3L, new actinide complexes were isolated, namely the dimeric thoriumcomplex [ThCl(L)]2 (1) and the monomeric uraniumcomplex UI(THF)(L) (2); under different crystallisation conditions, the dimeric uraniumcomplex is also isolated, [UI(L)]2 (2-dimer).
