Carboxylic acid-catalyzed highly efficient and selective hydroboration of alkynes with pinacolborane
Ho, Hon Eong,Asao, Naoki,Yamamoto, Yoshinori,Jin, Tienan
, p. 4670 - 4673 (2014)
We have demonstrated for the first time that carboxylic acids are able to catalyze the direct hydroboration of various terminal and internal alkynes with pinacolborane without using any metal catalysts. This unprecedented catalytic hydroboration exhibits
Copper-catalyzed dehydrogenative borylation of terminal alkynes with pinacolborane
Romero, Erik A.,Jazzar, Rodolphe,Bertrand, Guy
, p. 165 - 168 (2016)
LCuOTf complexes [L = cyclic (alkyl)(amino)carbenes (CAACs) or N-heterocyclic carbenes (NHCs)] selectively promote the dehydrogenative borylation of C(sp)-H bonds at room temperature. It is shown that σ,π-bis(copper) acetylide and copper hydride complexes are the key catalytic species.
Low-Coordinate NHC-Zinc Hydride Complexes Catalyze Alkyne C-H Borylation and Hydroboration Using Pinacolborane

Organozinc compounds containing sp, sp2, and sp3 C-Zn moieties undergo transmetalation with pinacolborane (HBPin) to produce Zn-H species and organoboronate esters (RBPin). This Zn-C/H-B metathesis step is key to enabling zinc-cataly

Paragraph 0034-036, (2021/10/16)
The invention discloses a hydroboration method of an aluminum chloride catalytic terminal group alkyne, and belongs to the technical field of boronation of terminal alkynes. To the method, the terminal group alkyne is added into the aluminum chloride with
ZnBr2-Catalyzed Dehydrogenative Borylation of Terminal Alkynes
Luo, Man,Qin, Yi,Chen, Xi,Xiao, Qian,Zhao, Binlin,Yao, Weiwei,Ma, Mengtao
, p. 16666 - 16674 (2021/11/18)
The simple, commercially available ZnBr2 has been successfully employed as a highly efficient and chemoselective catalyst for the dehydrogenative borylation of terminal alkynes with HBpin under mild conditions. It shows a good tolerance toward various functional groups such as aryl, alkyl, heteroaryl, etc. The plausible reaction mechanism has been investigated based on the corresponding stoichiometric experiments and DFT calculations.
Photoredox-Mediated Reaction of gem-Diborylalkenes: Reactivity Toward Diverse 1,1-Bisborylalkanes
Eghbarieh, Nadim,Kumar, Nivesh,Masarwa, Ahmad,Shames, Alexander I.,Stein, Tamar
supporting information, p. 5360 - 5364 (2020/04/23)
The use of gem-diborylalkenes as radical-reactive groups is explored for the first time. These reactions provide an efficient and general method for the photochemical conversion of gem-diborylalkenes to rapidly access 1,1-bisborylalkanes. This method expl

Persistent chlorine: Hydrogenation of borolane-substituted vinylic chlorides catalyzed by Ir-P N complexes greatly preserved the chlorine substituent on the hydrogenated product, with only 3-19 % of dechlorinated byproducts present after hydrogenation. Th
