Heterocycle arylation: New donor-asymmetric ferrocene bis-phosphanes structurally related to the ubiquitous 1,1’-bis(diphenylphosphanyl)ferrocene (dppf) equipped with bulky and electron-poor phosphatrioxaadamantyl substituents have been synthesized and converted into stable Pd(0) complexes. The complexes were applied as potent catalysts for Pd-mediated C−H bond arylation of benzoxazoles with aryl chlorides under low catalyst loading in an environmentally benign solvent.

带有磷酸三氧杂金刚烷基取代基的二茂铁双膦的稳定 Pd(0) 配合物有效催化芳基氯化物对苯并恶唑的选择性 CH 芳基化

杂环芳基化：新的供体不对称二茂铁双膦在结构上与普遍存在的 1,1'-双（二苯基膦酰基）二茂铁 (dppf) 相关，该二茂铁配备有庞大且缺电子的磷三氧杂金刚烷基取代基，并已被合成并转化为稳定的 Pd(0) 配合物. 在环境友好的溶剂中，在低催化剂负载下，该配合物被用作 Pd 介导的苯并恶唑与芳基氯的 CH 键芳基化的有效催化剂。
