  diverse amines. Various readily reducible functional groups, such as esters, alkynes, and alkenes, were well tolerated. Furthermore, the methodology was extended to the synthesis of bio- and drug-derived amines. Detailed mechanistic studies revealed a reaction pathway entailing aldehyde and amido complex formation via an unusual C–N bond cleavage-reformation process, followed by C–O bond cleavage.

  开发用于选择性合成胺的温和高效的催化方法是一个长期的研究目标。在这方面，催化脱氧酰胺还原已被证明是有前途但具有挑战性的，因为这种方法需要选择性的 C-O 键裂解。在此，我们报告了伯、仲和叔酰胺在室温下由地球丰富的金属催化剂 Zr-H 催化的选择性硼氢化反应，以获取不同的胺。各种易于还原的官能团，如酯、炔烃和烯烃，都具有良好的耐受性。此外，该方法还扩展到生物和药物衍生胺的合成。详细的机理研究揭示了一个反应途径，通过一个不寻常的 C-N 键断裂-重整过程形成醛和酰胺复合物，然后是 C-O 键断裂。

  日期：2020.3.22

  Replacing oxygen by sulfur atoms substantially changes the photophysical behavior of DBD dyes. While fluorescence quantum yields and lifetimes are decreased, absorption and emission wavelength markedly red‐shifted. The very large Stokes shifts should be especially emphasized. A series of S4‐DBD dyes with different electron withdrawing groups were prepared enabling a broad range of emission wavelength

  用硫原子代替氧会大大改变DBD染料的光物理行为。尽管荧光量子产率和寿命降低，但吸收和发射波长却发生了红移。应该特别强调很大的斯托克斯班次。制备了一系列具有不同吸电子基团的S 4 -DBD染料，可实现较宽的发射波长范围。
