(RTP) syntheses of reactive rare earth compounds from free rare earth metals, HgAr2, and a proligand HL. Thus, the lanthanoid pyrazolates, [Ln(Ph2pz)3(thf)3] (Ph2pz=3,5‐diphenylpyrazolate; Ln=La, 1, Ce, 2, Nd, 3, Tb, 4; thf=tetrahydrofuran), [Ln2(Ph2pz)4(OMe)2(dme)2]⋅2 dme (Ln=Ho, 5, Er, 6, Tm, 7, Lu, 8; dme=1,2‐dimethoxyethane), [Ln(Ph2pz)3(dme)2] (Ln=Dy, 9, Sm, 10), [Ln(tBu2pz)3(thf)2] (tBu2pz=3,
在由游离稀土金属,HgAr 2和配位体HL合成反应性稀土化合物的氧化还原金属转移/质子分解(RTP)中,三(五氟苯基)铋已被作为二芳基汞的潜在替代品进行了研究。因此,镧系元素吡唑酸盐[Ln(Ph 2 pz)3(thf)3 ](Ph 2 pz = 3,5-二苯基吡唑酸酯; Ln = La,1,Ce,2,Nd,3,Tb,4 ; thf =四氢呋喃),[LN 2(PH 2 PZ)4(OME)2(DME)2 ] ⋅ 2 DME(Ln为何,5,呃6,Tm,7,Lu,8;dme = 1,2-二甲氧基乙烷),[Ln(Ph 2 pz)3(dme)2 ](Ln = Dy,9,Sm,10),[Ln(t Bu 2 pz)3(thf)2 ](t Bu 2 pz = 3,5-二叔丁基吡唑酸酯; Ln = La,11,Ce,12,Sm,13,Gd,14,Dy,15,Ho,16,Tm,17,Yb,18,Lu,19),[Ln(ttfpz)3(thf)3
