The reactivity of the P butterfly complexes [{Cp'''Fe(CO)}(μ,η-P)] (A, Cp''' = CHBu) and [{CpCr(CO)}(μ,η-P)] (B, Cp = C(CH)) towards the N-heterocyclic carbene IMe (1,3,4,5-tetramethyl-imidazol-2-ylidene) is reported. The reaction of A affords [P(IMe)][Fe(CO)Cp'''] (1) or [P(IMe)][{Cp'''Fe}(μ,η-P)] (2), the latter possessing a P-allylic moiety. In contrast, the reaction of B yields [P(IMe)][Cr(CO)Cp*] (3) and [{CpCr(CO)}(η-PIMe)][Cr(CO)Cp] (4), featuring a novel metal-bridged P dumbbell.
报道了磷蝴蝶配合物[{Cp'''Fe(CO)}(μ,η-P)]（A，Cp''' = CHBu）和[{CpCr(CO)}(μ,η-P)]（B，Cp = C(CH)）对N-杂环卡宾IMe（1,3,4,5-四甲基-咪唑-2-亚基）的反应活性。A的反应生成[P(IMe)][Fe(CO)Cp''']（1）或[P(IMe)][{Cp'''Fe}(μ,η-P)]（2），后者含有一个P-烯丙基部分。相比之下，B的反应生成[P(IMe)][Cr(CO)Cp*]（3）和[{CpCr(CO)}(η-PIMe)][Cr(CO)Cp]（4），其具有一种新型的金属桥连P哑铃结构。
