azolium complexes leads to a mixture of and ad ducts.18—20 The products of further hydrosilylation of the double bonds in the adducts 1—3 were not formed under these conditions. Hydrosilanes undergo the addition to styrene in the presence of [nN(CH2CH2OH)3Rh] 3+•3Cl– (n = 1, 2). The reaction proceeds regioselectively with the forma tion of terminal adducts 4—6 (18—34% yield). The most efficient catalyst
三乙醇胺与金属盐 (MXp) 的离子络合物,通式 [nN(CH2CH2OH)3M] p+•pХ– (M = Mn, Co, Ni, Fe; X = Cl, OAc; n = 1, 2; p = 2, 3),类似于silatranes1具有环状“atrane”结构和分子内配位N→M键。然而,与 silatranes 相比,它们包含配位 HO→M 键,2-15 而不是共价 O-Si 键。我们表明,HMA 与 sila tranes 一样,表现出很高的生理活性。因此,HMA,其中 M = Mg、Fe、Co、Ni、Cu、Rh,具有免疫活性,8 而当 M = Zn 时,它们表现出抗血管生成和抗硬化作用。 12,13,15 最近,M = Ni、Co 被建议用作从水中光催化制备氢气的助催化剂,16 而对于 M = Cu — 作为芳基卤化物羟基化的催化剂。17 在目前的工作中,我们首次研究了 HMA [nN(CH2CH2OH)mM]
