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
无金属催化剂三(2,4,6-三氟苯基)硼烷已证明其在多种不饱和试剂的1,2-氢硼化中具有广泛的应用,这些不饱和试剂包括炔烃,醛和亚胺,其中包括大量的吸电子和捐赠功能。据报道,有超过50种硼化产物,在环境条件下,许多反应都是在低催化剂负载下进行的。在醛和亚胺的情况下,这些频哪醇硼酸酯可以容易地水解以留下相应的醇和胺,而炔基底物产生乙烯基硼烷。这对有机化学家来说具有很大的合成用途。
