研究了金属苯甲醚Os(CC(R)=C(CH3)C(R)=CH)Cl2(PPh3)(2)(R=SiMe3，H)的亲电取代反应。这些金属苯甲醚与亲电试剂，包括Br2、NO2BF4、NOBF4、HCl/H2O2和AlCl3/H2O2反应，生成相应的溴化、硝化、亚硝化和氯化产物。反应通常发生在金属循环的C2和C4位置。这些观察结果支持金属苯类化合物具有芳香性的观点。
The electrophilic substitution reactions of metallabenzynes Os( CC(R)=C(CH3)C(R)=CH)Cl-2(PPh3)(2) (R = SiMe3, H) were studied. These metallabenzynes react with electrophilic reagents, including Br-2, NO2BF4, NOBF4, HCl/H2O2, and AlCl3/H2O2 to afford the corresponding bromination, nitration, nitrosation, and chlorination products. The reactions usually occur at the C2 and C4 positions of the metallacycle. These observations support the notion that metallabenzynes exhibit aromatic properties.
