C(CH2Br)4 in thf gives (CH2TeMe)2 irrespective of the ratio of reactants, in contrast to the reaction with LiSeMe, which gives either C(CH2SeMe)4 or (CH2SeMe)2 depending upon the reaction conditions. The synthesis and properties of [ (CH2TeMe2)2]I2, (CH2TeMeI2)2, [Mn(CO)3Cl (CH2EMe)2}] (E = Se or Te) and [MCl(η6-p-cymene) (CH2EMe)2}]PF6 (M = Ru or Os) are described. X-ray crystal structures are reported
LiTeMe与C(CH 2 Br)4的反应在 (CH 2 TeMe)2,无论反应物的比例如何,与与LiSeMe的反应形成C(CH 2 SeMe)4或 (CH 2 SeMe)2取决于反应条件。[ (CH 2 TeMe 2)2 ] I 2, (CH 2 TeMeI 2)2,[Mn(CO)3 Cl (CH 2 EME)2 }](E =硒或Te)和[的MC1(η 6 - p -cymene) (CH 2 EMe)2 }] PF 6(M = Ru或Os)被描述。据报道X射线晶体结构[ (CH 2 TeMe 2)2 ] I 2,[Mn(CO)3 Cl (CH 2的Teme)2 }],[的MC1(η 6 - p -cymene) (CH 2 TeMe)2 }] PF 6(M = Ru,E = Se或Te,M = Os,E = Se)。与三亚甲基连接的类似物相比,配体主链中的环丙基环的作用是打开螯合环内的C
