  these molecules are assembled through the stepwise introduction of a reactivity handle in place of an aromatic C-H bond (that is, a nitro group, halogen or boronic acid) and a subsequent functionalization or cross-coupling. Here we show that aromatic amines can be constructed by direct reaction of arenes and alkyl amines using photocatalysis, without the need for pre-functionalization. The process

  用于制备芳香胺的碳-氮键的形成是全球范围内为生产高价值材料而进行的前五项反应之一，从原料化学品到药物和聚合物不等。由于这种普遍性和多样性，其制备方法影响了学术界和工业界的整个化学合成过程。通常，这些分子是通过逐步引入反应性手柄代替芳香族CH键（即硝基，卤素或硼酸）和随后的功能化或交叉偶联而组装而成的。在这里，我们表明，芳烃胺可以使用光催化作用，通过芳烃和烷基胺的直接反应来构建，而无需进行预功能化。该过程可以轻松准备高级构建基块，容忍的功能范围很广，并且可以通过批处理流协议来实现多克规模。通过对几种药物，农药，肽，手性催化剂，聚合物和有机金属配合物的修饰，证明了该策略作为后期功能化平台的优点。

  Applicants have unexpectedly discovered that catalysts made from a ruthenium catalyst precursor or preformed ruthenium catalysts as otherwise described in the present specification are capable of effecting the addition of a N-H bond across an olefin C=C (olefinic) bond of a substrate with a high degree of regioselectivity and enantioselectivity in high yield. These addition reactions proceed in an anti-Markovnikov or Markovnikov fashion depending upon the catalyst precursor used to generate the ruthenium catalyst which actually participates in the addition reaction. The present invention relates to methods of adding N-H bonds across an olefinic bond in a substrate, using a ruthenium catalyst precursor or catalyst I comprising a compound according to the general structure I: Formula (I) where Ru is a ruthenium atom; L1 represents one or more coordinated ancillary ligands, which may be all the same ligand or which may be a combination of different ligands, each of which may be neutral or formally charged, and each of which may be monodentate and coordinated to ruthenium through a single atom or which may be linked or chelated and bound through more than one atom; L2 represents one or more formally charged ligands which are the same or different and which are optionally susceptible to removal with a strong acid; and x is 0-6, preferably 1, y is 0-6, preferably 2 and n is 1-4, preferably 1.
