Reaction of the uranyl β-ketoiminate complex UO2(tBuacnac)2 (1) (tBuacnac = tBuNC(Ph)CHC(Ph)O) with Me3SiI, in the presence of Ph3P, results in the reductive silylation of the uranyl moiety and formation of the U(V) bis-silyloxide complex [Ph3PI][U(OSiMe3)2I4] (2). Subsequent reaction of 2 with Lewis bases, such as 2,2′-bipyridine (bipy), 1,10-phenanthroline (phen), and tetrahydrofuran (THF), results
在Ph 3 P存在下,铀酰β-酮亚胺酸络合物UO 2(tBu aacnac)2(1)(tBu aacnac = t Bu N C(Ph)CHC(Ph)O)与Me 3 SiI的反应导致铀酰部分的还原甲硅烷基化和U(V)双甲硅烷基氧化物络合物[Ph 3 PI] [U(OSiMe 3)2 I 4 ]的形成(2)。随后反应2具有Lewis碱的物质,例如2,2'-联吡啶(bipy),1,10-菲咯啉(phen)和四氢呋喃(THF),导致金属中心的进一步还原和U(IV)配合物U的分离(OSiMe 3)2 I 2(bipy)2(3),U(OSiMe 3)2 I 2(phen)2(4)和[U(OSiMe 3)2 I(THF)4 ] [I 3 ](5)。
