    Efficient synthesis of the cyclometalated complex fac-[Rh(ppy)3] (ppy=2-phenylpyridinato)
    摘要:
    A new convenient high-yield synthesis of the tris-cyclometalated complexes fac-[Rh(ppy)(3)] (4; ppy = 2-phenylpyridinato) was developed. Complex 4 was prepared in a kind of one-pot synthesis starting from in situ prepared [Rh(acac)(coe)(2)] (2) which was heated in refluxing 2-phenylpyridine for a short time. After purification by filtration over alumina, compound 4 was obtained in yields of 65%. Also [Rh(a-cac)(ppy)(2)] (3) was prepared in a similar manner by oxidative addition of Hppy in refluxing toluene in high yields. In contrast to previous findings with the analogous iridium compounds, there was not any hint at the formation of the isomer mer-[Rh(ppy)(3)] using similar reaction conditions as applied for iridium. Furthermore the compound [{Rh(mu-Cl)(ppy)(2)}(2)] (5) was prepared from [{Rh(mu-Cl)(coe)(2)}(2)] (1) and Hppy in refluxing toluene in nearly quantitative yield. (C) 2011 Elsevier B.V.

    已经开发了两种新的 Rh(I) 催化方法,通过将芳基硼酸添加到 N-叔丁烷亚磺酰基和 N-二苯基膦酰基亚胺来合成手性 α-支化胺。与使用格氏试剂或有机锂试剂的替代方法相比,该合成方法对官能团的耐受性更强,并且使用的亚胺活化基团很容易去除。这些方法都具有高产率(70-97% 的产率)和非常高的选择性(>93:7 dr 和 88-94% ee)。值得注意的是,N-叔丁烷亚磺酰基亚胺方法适用于具有烯醇化质子的脂肪族亚胺。此外,还开发了一种从醛合成 N-叔丁烷亚磺酰基保护的 α-支化胺的一锅法。

    日期:2006.2.1

    Three novel rhodium(I) acetylacetonato (acac) complexes bearing phosphinoalkynes (Ph2PC≡C-t-Bu, Ph2PC≡CPPh2, and Ph2PC≡CC≡CPPh2) have been prepared and characterized fully. Addition of B2cat3 (cat = 1,2-O2C6H4) to Rh(acac)(Ph2PC≡C-t-Bu)2 (1a) led to zwitterionic Rh(η6-catBcat)(Ph2PC≡C-t-Bu)2 (2a), the first example of this type of compound to contain monodentate phosphine ligands. All new rhodium complexes have been investigated for their ability to catalyse the hydroboration of vinylarenes.Key words: catalysis, hydroboration, phosphinoalkynes, regioselectivity, rhodium.
