  摘要：

  由于sp 3-杂化轨道的方向性和π轨道的缺乏，动力学和热力学稳定的C（sp 3）–C（sp 3）键的氧化裂解非常困难，并且仍很少进行探索。在这项工作中，在我们精心设计的C–C单键裂解机理的量子力学（QM）计算和精细实验的双重论证下，我们发现了一种光诱导选择性氧化C（sp 3）–C（sp 3）的方法。在非常温和的条件下，使用O 2作为良性氧化剂，通过简单的可见光照射即可轻松实现芳基胺中的键断裂。C（sp 3）–C（sp 3）键在吗啉/哌嗪芳基胺中具有出色的官能团耐受性。重要的是，我们的方法学值得注意，不仅因为它不需要任何催化剂，而且因为它为临床药物和天然产品的可扩展功能化提供了宝贵的可能性。

• Catalytic Hydrogenation of Amides to Amines under Mild Conditions
  作者：Mario Stein、Bernhard Breit

  DOI：10.1002/anie.201207803

  日期：2013.2.18

  Under (not so much) pressure: A general method for the hydrogenation of tertiary and secondary amides to amines with excellent selectivity using a bimetallic Pd–Re catalyst has been developed. The reaction proceeds under low pressure and comparatively low temperature. This method provides organic chemists with a simple and reliable tool for the synthesis of amines.

  We report sodium trihydroxyaryl borates as the first robust tetracoordinate organoboron catalysts for reductive functionalization of CO2. These catalysts, easily synthesized from condensing boronic acids with metal hydroxides, activate main group element–hydrogen (E–H) bonds efficiently. In contrast to BX3 type boranes, boronic acids and metal-BAr4 salts, under transition metal-free conditions, sodium

  我们报告三羟基芳基硼酸钠作为第一个坚固的四配位有机硼催化剂，用于CO 2的还原功能化。这些催化剂很容易从硼酸与金属氢氧化物的缩合反应中合成，可以有效地活化主族元素氢键。与BX 3型硼烷，硼酸和金属-BAr 4盐相比，在无过渡金属的条件下，三羟基芳基硼酸钠对各种胺（包括带有官能团的胺）表现出较高的还原性N-甲酰化反应性（106例）例如酯，烯烃，羟基，氰基，硝基，卤素，MeS–，醚基等。催化具有挑战性的吡啶胺的甲酰化反应的性能过高，为使用传统的甲酰化试剂提供了一种有前途的替代方法。机理研究支持将静电相互作用作为Si / B–H活化的关键，从而使碱金属硼酸盐成为用于CO 2加氢硼化，加氢硅烷化和还原甲酰化/甲基化的通用催化剂。

  DOI：10.1021/ol300781s

  日期：2012.5.4

  cleavage of aldehydes with dioxygen activation has been developed. The usage of molecular oxygen (1 atm) as oxidant, reactant, and an initiator to trigger this transformation makes this transformation very green and practical. A plausible radical process is proposed on the basis of mechanistic studies. Furthermore, this method provides a practical, neutral, and mild synthetic approach to formamides

  of harsh reaction conditions. This catalytic protocol affords a broad range of formylated products in moderate to excellent yields under mild reaction conditions with a high TON and TOF. The bulky boron (B(C6F5)3) catalyst reacts with amines and forms a Frustrated Lewis Pair (FLP) and activates CO2 and Me2NH·BH3 molecules. Additionally, this boron catalyst shows high catalytic activity for the cyclization

  在这项工作中，B（C 6 ˚F 5）3被用作过渡金属-自由有机催化剂Ñ使用二氧化碳（CO胺的-formylation 2），其为C1源和二甲胺硼烷（ME 2 NH·BH 3）作为绿色氢转移源，温度为80°C。大多数报道的工作利用硅烷和氢进行CO 2的N-甲酰化反应，迄今为止，这一直受到低原子经济性，高成本或苛刻的反应条件的限制。该催化方案可在温和的反应条件下以较高的TON和TOF提供中等至极好的收率的各种甲酰化产物。笨重的硼（B（C6 F 5） 3）催化剂与胺反应，形成失落的路易斯对（FLP），并活化CO 2和Me 2 NH·BH 3分子。另外，该硼催化剂对于使用CO 2和Me 2 NH·BH 3合成苯并咪唑的邻苯二胺的环化显示出高催化活性。
