Summary
Researchers synthesized rare transition metal tris(σ-B-H) borate complexes using a novel salt elimination method. These stable complexes feature three labile σ-B-H bonds, enabling H/D exchange and ligand substitution reactions.
Area of Science:
- Organometallic Chemistry
- Boron Chemistry
- Catalysis
Background:
- Transition metal-mediated B-H bond activation is crucial for catalysis.
- Most known complexes feature one or two σ-B-H bonds.
- Compounds with three σ-B-H bonds are exceptionally rare.
Purpose of the Study:
- To develop a facile synthesis for rare transition metal tris(σ-B-H) borate complexes.
- To investigate the properties and reactivity of these novel compounds.
- To explore new synthetic routes for borate complexes.
Main Methods:
- Salt elimination protocol using [Cp*RuCl]4 and lithium trihydroborates Li[ArBH3].
- Synthesis of tris(σ-B-H) borate complexes with 2,6-disubstituted aryl groups.
- Characterization of thermal stability in solution.
Main Results:
- Successful synthesis of rare transition metal tris(σ-B-H) borate complexes.
- Demonstrated remarkable thermal stability of the synthesized complexes.
- Observed H/D exchange with D2 and ligand substitution with PPh3, PCy3, and IPr2Me2.
Conclusions:
- This work provides a facile approach to synthesize tris(σ-B-H) borate complexes.
- The novel complexes exhibit unusual reactivity, including labile σ-B-H bonds.
- New synthetic pathways for both tris(σ-B-H) and bis(σ-B-H) borates are established.

01:26Radical Substitution: Hydrogenolysis of Alkyl Halides with Tributyltin Hydride
1.9K
Radical substitution reactions can be used to remove functional groups from molecules. The hydrogenolysis of alkyl halides is one such reaction, where the weak Sn–H bond in tributyltin hydride reacts with alkyl halides to form alkanes. Here, the reagent Bu3SnH yields tributyltin halide as a byproduct.
The bonds formed in this reaction are stronger than the bonds broken, making it energetically favorable. The reaction follows a radical chain mechanism similar to radical halogenation...

03:08Hydroboration-Oxidation of Alkenes
8.7K
In addition to the oxymercuration–demercuration method, which converts the alkenes to alcohols with Markovnikov orientation, a complementary hydroboration-oxidation method yields the anti-Markovnikov product. The hydroboration reaction, discovered in 1959 by H.C. Brown, involves the addition of a B–H bond of borane to an alkene giving an organoborane intermediate. The oxidation of this intermediate with basic hydrogen peroxide forms an alcohol.

02:42Valence Bond Theory
9.1K
Coordination compounds and complexes exhibit different colors, geometries, and magnetic behavior, depending on the metal atom/ion and ligands from which they are composed. In an attempt to explain the bonding and structure of coordination complexes, Linus Pauling proposed the valence bond theory, or VBT, using the concepts of hybridization and the overlapping of the atomic orbitals. According to VBT, the central metal atom or ion (Lewis acid) hybridizes to provide empty orbitals of suitable...

02:36Regioselectivity and Stereochemistry of Hydroboration
8.3K
A significant aspect of hydroboration–oxidation is the regio- and stereochemical outcome of the reaction.
Hydroboration proceeds in a concerted fashion with the attack of borane on the π bond, giving a cyclic four-centered transition state. The –BH2 group is bonded to the less substituted carbon and –H to the more substituted carbon. The concerted nature requires the simultaneous addition of –H and –BH2 across the same face of the alkene giving syn...

In most main group element compounds, the valence electrons of the isolated atoms combine to form chemical bonds that satisfy the octet rule. For instance, the four valence electrons of carbon overlap with electrons from four hydrogen atoms to form CH4. The one valence electron leaves sodium and adds to the seven valence electrons of chlorine to form the ionic formula unit NaCl (Figure 1a). Transition metals do not normally bond in this fashion. They primarily form coordinate covalent bonds, a...

2.2K
Recently, the development of olefin metathesis polymerization advanced the field of polymer synthesis. Simply put, the reorganization of substituents on their double bonds between two olefins in the presence of a catalyst is known as the olefin metathesis reaction. The use of metathesis reaction for polymer synthesis is called olefin metathesis polymerization.
