Abstract A mild and efficient one-pot reductive monoalkylation of nitroarenes has been described using aldehydes as alkylating agents, molecular hydrogen as a reducing agent, and PtO2 as a catalyst in methanol. This methodology is found to be applicable for both aliphatic and aromatic aldehydes and for a wide variety of nitroarenes. Supplemental materials are available for this article.

Boroaminomethylation of olefins with CO as −CH2-source via the mechanism of a carbene insertion into the N−H bond was described. In the present of CuCl and Xantphos as the catalyst, a variety of γ-boryl amines were obtained with broad functional groups tolerance. The new aromatization and other transformations of the γ-boryl amines demonstrate their utility. Notably, 13C labeled product was produced
描述了通过将卡宾插入 N-H 键的机制,以 CO 作为 -CH 2源的烯烃的硼氨基甲基化。在CuCl和Xantphos作为催化剂的作用下,得到了多种具有广泛官能团耐受性的γ-硼基胺。γ-硼基胺的新芳构化和其他转化证明了它们的实用性。值得注意的是,13 C 标记产品是用同位素标记的13 CO 生产的。
