  摘要：

  由LnI 3 THF n和3 equiv高收率合成同质三（烷基）稀土配合物Ln {C（SiHMe 2）3 } 3（Ln = La，1a ; Ce，1b ; Pr，1c ; Nd，1d）的KC（SiHMe 2）3。X射线衍射研究表明1a - d是同构的伪C 3对称分子，每个烷基配体包含两个次级Ln↼HSi相互作用（总共六个）。与Ln {C（SiDMe 2）3 }比较可支持光谱分配3和DFT计算。Ln↼HSi和末端SiH在室温下在NMR时间尺度上快速交换，但两个基序在低温下可分辨。变温NMR研究提供用于交换过程激活参数在1A（Δ ħ ⧧ = 8.2（4）千卡·摩尔-1 ;Δ小号⧧ = -1（2）卡·摩尔-1 ķ -1）和1A〜d 9（Δ ħ ⧧ = 7.7（3）千卡·摩尔-1 ;Δ小号⧧ = -4（2）卡·摩尔-1 ķ -1）。线形比较，速率常数（k H/ ķ d），和ln（斜率ķ / Ť）与1

  摘要：

  Benzene, toluene, tert-butylbenzene, or biphenyl virtually do not react with NdI2 (1) or DyI2 (2) in THF at -20degreesC but appreciably accelerate the reactions of these salts with solvents, resulting in LnI(3) and intractable mixtures of products of the general composition [LnI(H)(R)(THF)] (R are fragments of the THF molecule). The same effect is induced by the addition of diphenylmercury or tetraphenyltin to solutions of 1 or 2. Phenol easily oxidizes 1 and 2 to give at 0 degreesC the PhOLnI(2)(THF)(x) complexes (x = 3, 4) in 55-95% yields. At -90 degreesC, iodide 2 is converted into a similar complex PhODyI2(THF)(4), whereas 1 gives a mixture of PhONdI2(THF)(4), (PhO)(2)NdI(THF)(5), NdI3(THF)(3), and [NdI(H)R(THF)]. A plausible pathway of the reactions including the intermediate formation of extremely reactive monovalent lanthanide iodides LnI is discussed.

  The reaction of NdI2 or DyI2 with VCl3 and cyclopentadiene in THF at 65–70 °C without isolation of the intermediates afforded vanadocene in 55 and 68% yields, respectively. An analogous reaction of DyI2 with CoCl2 at 50 °C produced Cp2Co in 38% yield.

  The diiodides NdI2 and DyI2 react with nitrogen at an atmospheric pressure at 2704-550 °C to give the nitrides (LnI2)3N (Ln = Nd and Dy). The products obtained are insoluble in organic solvents; in THF, they rapidly disproportionate into LnI3(THF)3 and the iodide nitrides (NdI)3N2 of unclear structures. The nitrides (NdI2)3N and (DyI2)3N can be completely hydrolyzed into ammonia, the triiodide hydrates LnI3(H2O)2, and the monoiodide hydrates LnI(OH)2(H2O). A reaction of (NdI2)3N with excess iodobenzene in THF gives Ph3N and PhNH2 in 9 and 5% yields, respectively. Reactions of (NdI2)3N with propyl chloride, benzyl chloride, and acetyl chloride produce no nitrogen-containing products. A reaction of (NdI2)3N with CpK gives Cp3Nd(THF) in 63% yield.

  Abstract The reaction of [(NdI)3N2] (I) with Cp3Er in the presence of sulfur in THF gave CpNdI2(THF), NdI(S2N2)(THF), and an unidentified erbium compound. A similar reaction of [(DyI)3N2] yielded CpDyI2(THF) and ErI(S2N2)(THF). When I reacted with ErCl3, the clusters [Nd2ErClI4-(S2)(S2N2)(THF)7] and [Nd2ErCl2I3(S2)(S2N2)(THF)7] were formed in 33–34% yield. From the mixture of reaction products of [(DyI)3N2]
