无金属催化剂三(2,4,6 -三氟苯基)硼烷在许多不饱和试剂(即炔、醛和亚胺)的1,2 -硼氢化反应中具有广泛的应用,这些试剂具有广泛的吸电子和供电子功能。报道了50多种硼化产物,许多反应在环境条件下以低催化剂负载进行。在醛和亚胺的情况下,这些松醇硼酸酯可以很容易地水解得到相应的醇和胺,而炔基底物则产生乙烯基硼烷。这对有机化学家在合成方面有很大的用处。
The metal‐free catalyst tris(2,4,6‐trifluorophenyl)borane has demonstrated its extensive applications in the 1,2‐hydroboration of numerous unsaturated reagents, namely alkynes, aldehydes and imines, consisting of a wide array of electron‐withdrawing and donating functionalities. A range of over 50 borylated products are reported, with many reactions proceeding with low catalyst loading under ambient conditions. These pinacol boronate esters, in the case of aldehydes and imines, can be readily hydrolyzed to leave the respective alcohol and amine, whereas alkynyl substrates result in vinyl boranes. This is of great synthetic use to the organic chemist.
