Addition of KSCPh3 to [U(NR2)3] (R = SiMe3) in tetrahydrofuran, followed by addition of 18-crown-6, results in formation of the U(IV) sulfide, [K(18-crown-6)][U(S)(NR2)3] (1) and Gomberg's dimer. Similarly, addition of KOCPh3 to [U(NR2)3] in tetrahydrofuran, followed by addition of 18-crown-6, results in formation of the U(IV) oxide, [K(18-crown-6)][U(O)(NR2)3] (3).

在
四氢呋喃中将 KSCPh3 添加到 [U(NR2)3] (R = SiMe3),然后添加 18-crown-6,导致形成 U(IV)
硫化物 [K(18-crown-6)] [U(S)(NR2)3] (1) 和 Gomberg 的二聚体。类似地,将 KOCPh3 添加到
四氢呋喃中的 [U(NR2)3],然后添加 18-crown-6,导致形成 U(IV) 氧化物,[K(18-crown-6)][U( O)(NR2)3] (3)。在此转化中还观察到三苯甲基阴离子 [K(18-crown-6)(THF)2][CPh3] (5) 和 U(IV) 醇盐 [U(OCPh3)(NR2)3] ( 4)。
