2‐substituted‐1‐amino‐o‐carboranes 2‐R‐1‐NH₂‐ o‐C₂B₁₀H₁₀ (R=CH₃, 1a; R=Ph, 1b) were synthesized and the reactions of these compounds with the yttrium dialkyl complex [Y(L)(CH₂SiMe₃)₂] (L=[2‐(2, 5‐Me₂C₄H₂N)C₆H₄NC(Ph)=NDipp]^-, Dipp=2, 6‐ⁱPr₂C₆H₃) were investigated. The ¹H NMR spectroscopy indicate that the reaction of ytrrium dialkyl complex with one equivalent of 2‐R‐1‐NH₂‐ o‐C₂B₁₀H₁₀ produce the mixture of ytrrium alkyl‐amido complex [Y(L)(2‐R‐1‐NH‐ o‐C₂B₁₀H₁₀)(CH₂SiMe₃)] (R=CH₃, 2a; R=Ph, 2b) and bis(amido) complex [Y(L)(2‐R‐1‐NH‐ o‐C₂B₁₀H₁₀)2] (R=CH₃, 3a; R=Ph, 3b). The yttrium bridging imido complex [Y(L)(2‐CH₃‐1‐N‐ o‐C₂B₁₀H₁₀)]2 (4a) was obtained by heating the mixture at 55 ℃ for 12 h. Complex 3a was isolated and characterized by treating the yttrium dialkyl complex with two equivalents of 1a. The structures of complexes 3a and 4a were verified by single‐crystal X‐ray diffraction..
