  日期：2021.4

  mononuclear metal hydrides are unknown in nature, despite the prevalence of such intermediates in the reactions of synthetic transition-metal catalysts. If metalloenzymes could react through abiotic intermediates like these, then the scope of enzyme-catalysed reactions would expand. Here we show that zinc-containing carbonic anhydrase enzymes catalyse hydride transfers from silanes to ketones with high enantioselectivity

  尽管在合成过渡金属催化剂的反应中普遍存在此类中间体，但通过单核金属氢化物的酶促反应在自然界中是未知的。如果金属酶可以通过这样的非生物中间体发生反应，那么酶催化反应的范围将会扩大。在这里，我们展示了含锌碳酸酐酶以高对映选择性催化氢化物从硅烷到酮的转移。我们报告的机械数据提供了强有力的证据，表明该过程涉及单核氢化锌。这项工作表明，非生物硅烷可以在酶催化过程中充当还原当量，并且在质子环境中通常不稳定的正电金属的单体氢化物可以作为酶促过程中的催化中间体。总体，

  Direct oxidative C(sp)−H/C(sp3)−H cross‐coupling offers an ideal and environmentally benign protocol for C(sp)−C(sp3) bond formations. As such, reactivity and site‐selectivity with respect to C(sp3)−H bond cleavage have remained a persistent challenge. Herein is reported a simple method for iron‐catalyzed/silver‐mediated tertiary alkylation of terminal alkynes with readily available and versatile 1

  直接氧化的C（sp）-H / C（sp 3）-H交叉偶联为C（sp）-C（sp 3）键的形成提供了理想的环境友好方案。因此，相对于C（sp 3）-H键裂解的反应性和位点选择性仍然是一个持续的挑战。本文报道了一种简便易行的方法，可利用易于获得的通用1,3-二羰基化合物对末端炔烃进行铁催化/银介导的叔烷基化。该反应适用于多种底物，即使使用含有其他叔，苄基和C（sp 3）-H将α键合至杂原子。对产品的精心设计使得可以合成一系列通用的构建基块。对照实验暗示了以碳为中心的第三级自由基物种的原位生成。
