A novel TEMPO-catalyzed aerobic oxygenation and nitrogenation of hydrocarbons via C═C double-bond cleavage has been disclosed. The reaction employs molecular oxygen as the terminal oxidant and oxygen-atom source by metal-free catalysis under mild conditions. This method can be used for the preparation of industrially and pharmaceutically important N- and O-containing motifs, directly from simple and
已经公开了一种通过 C=C 双键裂解的新型 TEMPO 催化的碳氢化合物有氧氧化和氮化。该反应采用分子氧作为末端氧化剂和氧原子源,在温和条件下通过无金属催化进行。该方法可用于直接从简单易得的烃类制备工业和药学上重要的含 N 和 O 基序。

The synthesis of E-alkenylstannanes fromaldehydes and a mixture of Bu3SnCHBr2, LiI and CrCl2 is described. A mechanism is proposed to account for the alkene geometry in chromium(II)-mediated alkene synthesis which involves stereoselective addition by a gem-dichromium reagent to an aldehyde followed by a stereospecific elimination step.
