We report herein the actinide-mediated insertion of E-H bonds (E = C, N, P, S) into various heterocumulenes including carbodiimides, isocyanates, and isothiocyanates. The precatalysts are prepared by a simple, one-pot procedure using readily available starting materials, and challenging insertions are achieved with excellent selectivity in short reaction times. Spectroscopic data are utilised to propose the active catalytic mechanism and derive thermodynamic activation parameters, which are described in this study. The only example of an actinide-mediated C-H bond insertion into a carbon-heteroatom bond is presented within this study.
我们在此报告了锕系元素介导的E-H键（E = C、N、P、S）插入各种杂累积烯烃，包括碳二亚胺、异氰酸酯和异硫氰酸酯的反应。预催化剂通过使用易得的起始原料，采用简单的一锅法制备，并且在短反应时间内以优异的选择性实现了具有挑战性的插入反应。利用光谱数据提出了活性催化机理并推导了热力学活化参数，本研究对此进行了描述。本研究展示了锕系元素介导的C-H键插入碳-杂原子键的唯一实例。
