    Copper-Catalyzed Hydroboration of Carbon Dioxide
    摘要:
    A copper/N-heterocyclic carbene catalyzed hydroboration of carbon dioxide has been developed to give a formic acid derivative selectively under mild conditions. Investigations directed toward understanding the catalytic cycle of this process have been carried out, and the hydroboration product can be directly used as a formylation reagent for various amines.

    While numerous organo(metallic)catalyst systems were documented for dearomative hydroboration of N‐aromatics, alkoxide base catalysts have not been disclosed thus far. Described herein is the first example of alkoxide‐catalyzed hydroboration of N‐heteroaromatics including pyridines, providing a broad range of reduced Nheterocycles with high efficiency and selectivity. Mechanistic studies revealed
    尽管有许多有机(金属)催化剂体系被记录用于N-芳烃的脱芳烃硼氢化反应,但迄今为止尚未公开醇盐基催化剂。本文介绍的是烷氧基催化的N-杂芳族化合物(包括吡啶)的硼氢化反应的第一个实例,可提供范围广泛的还原N-杂环,具有高效率和选择性。机理研究揭示了前所未有的违反直觉的脱芳香化途径,其中1)吡啶-BH 3加合物受到烷氧基硼氢化物的氢化物攻击,2)原位生成的BH 3充当催化促进剂,3)1,4-二氢吡啶基硼氢化物处于主要的休息状态。

The active catalyst is proposed to be a La-hemiacetal, [(Me3Si)2N]2La-OCHR(OR)[HBpin], generated in situ from LaNTMS via hydroboronolysis of a single La–N(SiMe3)2 bond. These results add to the growing compendium of selective oxygenate transformations that LaNTMS is competent to catalyze, further underscoring the value and versatility of

    Catalytic reduction of esters is a favourable synthetic strategy to obtain the corresponding alcohols. La(CH2C6H4NMe2-o)3, a simple and facilely accessible lanthanide complex, can serve as a highly efficient catalyst for the reduction of esters with pinacolborane (HBpin), selectively affording alcohols in good yields under mild conditions. This protocol exhibits good tolerance for many functional groups
