The boron group is notable for trends in the electron configuration, as shown above, and in some of its elements' characteristics. Boron differs from the other group members in its hardness, refractivity and reluctance to participate in metallic bonding. An example of a trend in reactivity is boron's tendency to form reactive compounds with ...
Most reactions transfer a nucleophilic boron substituent to an electrophilic center either inter- or intramolecularly. In particular, α,β -unsaturated borates and borates with an α leaving group are highly susceptible to intramolecular 1,2-migration of a group from boron to the electrophilic α position.
Elemental boron, boron oxide, boric acid, borates, and many organoboron compounds are relatively nontoxic to humans and animals (with toxicity similar to that of table salt). The LD 50 (dose at which there is 50% mortality) for animals is about 6 g per kg of body weight.
The product of carboboration reactions are organoborane compounds which prove to be useful in organic synthesis, containing both a new carbon group and a boron handle for further functionalization. This carbon-boron bond allows for organoboron chemistry , which facilitates a wide variety of chemical transformations such as oxidation and the ...
The reactivity of triboracyclopropenyl-containing compounds is relatively under-explored, as only one example has been prepared in the solution phase. The compound reported by Braunschweig, Na 4 [B 3 (NCy 2 ) 3 ] 2 • 2 DME, is an extremely potent reductant with an oxidation potential of -2.42 V vs. the ferrocene/ferrocenium couple.
[1] [2] The most common example of compounds with 13/15 group multiple bonds are those with B=N units. The boron-nitrogen-hydride compounds are candidates for hydrogen storage. [3] [4] [5] In contrast, multiple bonding between aluminium and nitrogen Al=N, Gallium and nitrogen (Ga=N), boron and phosphorus (B=P), or boron and arsenic (B=As) are ...
Ball-and-stick model of superconductor magnesium diboride. Boron atoms lie in hexagonal aromatic graphite-like layers, with a charge of −1 on each boron atom. Magnesium(II) ions lie between layers. Binary metal-boron compounds, the metal borides, contain boron in negative oxidation states. Illustrative is magnesium diboride (MgB 2). Each ...
It features a boron hydride functional group incorporated in a five-membered C 2 O 2 B ring. Like related boron alkoxides, pinacolborane is monomeric. It is a colorless liquid. [2] It features a reactive B-H functional group. [3]
