- A highly efficient cobalt-catalyzed deuterogenolysis of diboron: Synthesis of deuterated pinacolborane and vinylboronates
-
Highly efficient hydrogenolysis and deuterogenolysis of diboron compounds have been realized by the use of a cobalt catalyst, affording TON up to 48201. Furthermore, a one-pot two-step procedure comprising sequential deuterogenolysis of diboron and deuteroboration of alkynes under the same cobalt catalyst has been developed for the efficient, atom-economical synthesis of deuterated vinylboronates with high deuterium incorporation and excellent regio- and stereoselectivity.

- A process for preparing a diboron ester (by machine translation)
-
The invention discloses a process for preparing a diboron ester. Borane complexes and corresponding diol reaction and produce corresponding mellow borane, the iron then took place in the presence of catalyst to self-coupling forming a diboron ester. Short synthesis steps of the method, high safety, mild reaction conditions, suitable for many kinds of a diboron ester synthesis. (by machine translation)

- PROCESS FOR PRODUCING 1,3,2-DIOXABORINANE COMPOUNDS
-
A process for producing a 1,3,2-dioxaborinane compound of the general formula (I) in which each R individually is selected from the group consisting of H and C1-8-alkyl, by reacting a diol of the general formula (II) [in-line-formulae]HO—CRR—CRR—CRR—OH ??(II)[/in-line-formulae]with diborane is performed without using a solvent.

- Efficient borylation of reactive aryl halides with MPBH (4,4,6-trimethyl-1,3,2-dioxaborinane)
-
The combination of 4,4,6-trimethyl-1,3,2-dioxaborinane, a particularly stable and inexpensive borylation reagent, and Buchwalds palladium catalyst provides a simple, fast, cost-effective borylation of electron-rich, reactive iodides, bromides, and triflates to produce stable, easily purified boronic esters.

- Improved preparation of 4,6,6-trimethyl-1,3,2-dioxaborinane and its use in a simple [PdCl2(TPP)2]-catalyzed borylation of aryl bromides and iodides
-
We describe a convenient preparation of 4,6,6-trimethyl-1,3,2-dioxaborinane (MethylPentaneDiolBorane, MPBH) and demonstrate that it is an excellent reagent for the [PdCl2(PPh3)2]-catalyzed borylation of aryl bromides and iodides. The corresponding boronic esters undergo rapid Suzuki coupling reactions in the presence of cesium fluoride. Thus, MPBH is an excellent alternative to pinacolborane for Pd-catalyzed borylation and cross-coupling reactions. Wiley-VCH Verlag GmbH & Co. KGaA, 2008.

-
The palladium-catalyzed borylation of aryl iodides with 4,4,6-trimethyl-1,3,2-dioxaborinane is described. The mild reaction conditions employed allow for aryl iodides with a wide variety of functional groups to be tolerated. The products of this borylation were coupled with aryl halides to give biaryls in good yields. Georg Thieme Verlag Stuttgart.
