摘要：

Treatment of [NaUN*(C,N)(2)][N* = N(SiMe3)(2); C, N = CH2-SiMe2N(SiMe3)] with I-2 led to the formation of the larger metallacycle [UN*(N{SiMe3}SiMe2CH2CH2SiMe2N{SiMe3})I] resulting from U-C cleavage and C-C coupling. Reaction of [NaUN*(O,N)(2)] [O,N = OC(=CH2)SiMe2N(SiMe3)] with I-2 afforded the U-V complex [Na{UN*(O,N)(2)}(2)(mu-I)] which was converted into the mononuclear azido derivative [NaUN*(O,N)(2)(N-3)]. This latter was not transformed into the neutral U-VI derivative in the presence of I-2 but afforded [U-V(N{SiMe3}SiMe2C{CHI}O)(2)I(THF)], resulting from a cascade of addition, substitution and protonolysis reactions.
