2,2'-亚甲基双(4,4,5,5-四甲基-1,3,2-二氧杂戊硼烷) | bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)methane | 78782-17-9 | C13H26B2O4 | 267.969 |
Regioselective hydroboration of terminal and internal alkynes is realized by using copper powder (0.3–1 μm) as a catalyst without any ligand.
Nano-copper ferrite supported Cu catalysts are active for hydroboration of alkynes to vinylboronates.
