    三(1-金刚烷基)膦:扩展了有机磷化合物的电子释放特性边界
    摘要:
    我们在这里报告了 PAd3 的显着特性,PAd3 是一种结晶的空气稳定固体,可通过可扩展的 SN1 反应获得。光谱数据显示,PAd3 受益于大烃基固有的极化性,表现出超出其他烷基膦的意外电子释放特性,并落在以 N-杂环卡宾为主的范围内。在低 Pd 负载下氯(杂)芳烃(40 个例子)的 Suzuki-Miyaura 交叉偶联过程中,PAd3 还具有显着的催化作用,包括商业药物的后期功能化。从氯芳烃合成缬沙坦和啶酰菌胺的工业前体在 10 分钟内具有 ~2 × 10(4) 周转率,证明了卓越的时空产率。

  • Highly Efficient Monophosphine-Based Catalyst for the Palladium-Catalyzed Suzuki−Miyaura Reaction of Heteroaryl Halides and Heteroaryl Boronic Acids and Esters

    In one aspect, phosphine compounds comprising three adamantyl moieties (PAd3) and associated synthetic routes are described herein. Each adamantyl moiety may be the same or different. For example, each adamantyl moiety (Ad) attached to the phosphorus atom can be independently selected from the group consisting of adamantane, diamantane, triamantane and derivatives thereof. Transition metal complexes comprising PAd3 ligands are also provided for catalytic synthesis including catalytic cross-coupling reactions.

  • Efficient Suzuki−Miyaura Coupling of (Hetero)aryl Chlorides with Thiophene- and Furanboronic Acids in Aqueous <i>n-</i>Butanol
    作者:Christoph A. Fleckenstein、Herbert Plenio
    DOI:10.1021/jo8001886
    日期:2008.4.1
    An efficient Suzuki cross-coupling protocol enables the reaction of N-hetero and normal aryl chlorides with thiophene- and furanboronic acids. Coupling is effected in aqueous n-butanol as the solvent in near quantitative yield with a catalyst loading of 0.1 - 1 mol %. For heterocyclic substrates aqueous catalysis is found to be more efficient than Suzuki coupling under anhydrous conditions. The developed Suzuki coupling procedure utilizes biodegradable solvents and is useful for large scale reactions, as it includes the facile product separation from a biphasic solvent mixture without the need for additional organic solvents during workup.
