    当前的发明涉及二烷基(2,4,6-或2,6-烷氧基苯基)膦或其四氟硼酸盐的结构、合成,以及其在钯催化的碳-氯键活化苏齐反应和碳-氮键形成反应中的应用。二烷基(2,4,6-或2,6-烷氧基苯基)膦或其四氟硼酸盐可以与钯催化剂配位,高度选择性地活化惰性碳-氯键,并催化与芳基硼酸或有机胺进行苏齐偶联反应或碳-氮键形成反应。当前的发明仅使用一步合成二烷基(2,4,6-或2,6-烷氧基苯基)膦,其四氟硼酸盐在空气中稳定。与已知用于活化碳-氯键的配体的合成路线相比,当前发明的方法简短、易操作。此外,使用这种类型的配体,光学活性氯代内酯和芳基硼酸的苏齐偶联产物将保持其构型和光学纯度。

  • Pd-catalyzed Suzuki coupling reaction of chloroalkylidene-β-lactones with LB-Phos as the ligand
    作者:Pengbin Li、Bo Lü、Chunling Fu、Shengming Ma
    DOI:10.1039/c2ob26365c
    日期:——
    In this paper, LB-Phos·HBF4 salt has been applied for the Pd-catalysed Suzuki coupling reactions of optically active (Z)-α-choroalkylidene-β-lactones. Aryl, vinyl, alkyl and heteroaromatic boronic acids may be coupled with optically active β-lactones affording corresponding optically active products highly selectively and efficiently.

    The current invention relates to the structure, synthesis of dialkyl(2,4,6- or 2,6-alkoxyphenyl)phosphine or its tetrafluoroborate, as well as its applications in the palladium catalyzed carbon-chlorine bond activation for Suzuki coupling reactions and carbon-nitrogen bond formation reactions. The dialkyl(2,4,6- or 2,6-alkoxyphenyl)phosphine or its tetrafluoroborate could coordinate with the palladium catalyst to activate the inert carbon-chlorine bond highly selectively and catalyze Suzuki coupling reaction with arylboronic acid or carbon-nitrogen bond formation reaction with organic amines. The current invention uses only one step to synthesize dialkyl(2,4,6- or 2,6-alkoxyphenyl)phosphine and its tetrafluoroborate is stable in the air. Compared with known synthetic routes of ligands used in activating carbon-chlorine bonds, the method of current invention is short, easy to operate. Moreover, with this type of ligands, the Suzuki coupling products of optically active chlorolactones and arylboronic acids would maintain their configuration and optical purity.
