preparation and characterization of a series of neutral rare‐earth metal complexes [Ln(Me3TACD)(η3‐C3H5)2] (Ln=Y, La, Ce, Pr, Nd, Sm) supported by the 1,4,7‐trimethyl‐1,4,7,10‐tetraazacyclododecane anion (Me3TACD−) are reported. Upon treatment of the neutral allyl complexes [Ln(Me3TACD)(η3‐C3H5)2] with Brønsted acids, monocationic allyl complexes [Ln(Me3TACD)(η3‐C3H5)(thf)2][B(C6X5)4] (Ln=La, Ce, Nd, X=H, F)
一系列中性稀土类金属配合物的[LN(我的制备和表征3 TACD)(η 3 -C 3 H ^ 5)2 ](Ln为Y,镧,铈,镨,钕,钐)由所述支撑1,4,7-三甲基1,4,7,10-四阴离子(ME 3 TACD - )的报告。处理后的中性烯丙基配合物的[LN(ME 3 TACD)(η 3 -C 3 H ^ 5)2 ]与布朗斯台德酸,单阳离子烯丙基配合物[LN(ME 3 TACD)(η 3 -C 3 H ^ 5)(THF )2 ] [B(C 6X 5)4 ](Ln = La,Ce,Nd,X = H,F)被分离并表征。氢解得到氢化物配合物[Ln(Me 3 TACD)H 2 ] n(Ln = Y,n= 3; La,n= 4; Sm)。X射线晶体学显示氢化镧为四核。[LN(我的反应性研究3 TACD)R 2 ] Ñ(R =η 3 -C 3 H ^ 5,Ñ = 0; R = H,Ñ = 3,4)朝呋喃衍生物包括下开环氢化硅烷化和脱氧情况。
