Well‐defined manganese complexes based on inexpensive, readily available ligands, 2,2′:6′,2′′‐terpyridine and its derivatives have been prepared and employed for the selective hydroboration of alkenes, ketones and aldehydes. Highly Markovnikov regioselective hydroboration of styrenes as well as excellent chemoselective hydroboration of ketones over alkenes were achieved, for the first time, by an earth‐abundant
基于廉价的,易于获得的配体2,2':6',2''-吡啶和其衍生物的良好定义的锰络合物已经制备出来,并用于烯烃,酮和醛的选择性加氢硼化。首次使用富地球的锰催化剂实现了苯乙烯的高度马尔可夫尼科夫区域选择性硼氢化反应以及酮在烯烃上的优异化学选择性硼氢化反应。
