The first example of the addition of an ambident nucleophile's endocyclic center to a coordinated isocyanide is reported, namely, the Pd^II- and Pt^II-mediated reaction of aryl isocyanides with N-methylimidazole- and N-methyltriazole-2-thiones resulting in C,S-chelated deprotonated diaminocarbene complexes. The obtained complexes were isolated in good yields (88–95%) and characterized by elemental analysis (C, H, N), high-resolution mass spectrometry, and IR, 1D (¹H, ¹³C, ¹⁹⁵Pt) and 2D (¹H–¹H COSY, ¹H–¹H NOESY, ¹H–¹³C HSQC, ¹H–¹³C HMBC) NMR spectroscopies, as well as by single-crystal X-ray diffraction for the four complexes. The favorability of the resulting regioselectivity was confirmed by DFT calculations.

PdII和PtII介导的芳基异氰化物与N-杂环硫酮的偶联

据报道，第一个将亲核试​​剂的内环中心加成到配位异氰酸酯上的例子是，Pd ^II-和Pt ^II介导的芳基异氰酸酯与N-甲基咪唑和N-甲基三唑-2-硫酮的反应，导致C ，S-螯合的去质子化的二氨基卡宾配合物。获得的复合物以良好的收率（88–95％）分离，并通过元素分析（C，H，N），高分辨率质谱和IR，1D（¹ H，¹³ C，¹⁹⁵ Pt）和2D（¹ H– ¹ H舒适度，¹ H– ¹ H噪音，¹ H– ¹³C HSQC，¹ H– ¹³ C HMBC）NMR光谱学，以及四种配合物的单晶X射线衍射。通过DFT计算证实了所得区域选择性的有利性。
