The combined use of aminocarbene and divinyltetramethyldisiloxane (dvtms) as supporting ligands enables the access of unprecedented low-coordinate iron(0) alkene compounds [L(n)Fe(η(2):η(2)-dvtms)] (L=N-heterocyclic carbene (NHC) or cyclic (alkyl)(amino)carbene (CAAC), n=1 or 2) from the reactions of FeCl2 with alkali-metal reducing agents, free aminocarbene ligands, and dvtms. The iron(0) species deliver their {L(n)Fe(0)} fragments to perform redox reactions with Ph2SiH2, S8, Se, and DippN3, furnishing novel aminocarbene-supported iron(IV) silylene, all-ferrous iron-sulfur/selenium cubanes, and bis(imido)iron(IV) compounds. These conversions demonstrate the potential synthetic utility of the carbene-supported iron(0) complexes as a valuable class of low-coordinate iron(0) reagents.
氨基卡宾和二乙烯基四甲基二硅氧烷（dvtms）的联合使用作为支持配体，使前所未有的低配位铁（0）烯烃化合物[L（n）Fe（η（2）：η（2）-dvtms）]（L=N-杂环卡宾（NHC）或环状（烷基）（氨基）卡宾（CAAC），n=1 或 2）能够从 FeCl2 与碱金属还原剂、游离氨基卡宾配体和 dvtms 的反应中获得。铁（0）物种将其{L（n）Fe（0）}片段传递给 Ph2SiH2、S8、Se 和 DippN3，进行氧化还原反应，生成新型氨基卡宾负载的铁（IV）硅烯、全二价铁-硫/硒立方烷和双（亚氨基）铁（IV）化合物。这些转化证明了作为一类有价值的低配位铁（0）试剂的负载卡宾的铁（0）配合物具有潜在的合成用途。
