Direct functionalization at the boron center of antiaromatic chloroborole.
نویسندگان
چکیده
The presence of a reactive B-Cl bond allowed for the direct functionalization of the boron center in antiaromatic chloroborole ClBC4Ph4, thus allowing for a selective fine tuning of the optical properties of borole derivatives and facilitating a potential new approach toward the introduction of borole moieties into the backbone of organic pi-conjugated frameworks.

Hydrocarbon analogues of boron clusters--planarity, aromaticity and antiaromaticity.
An interesting feature of elemental boron and boron compounds is the occurrence of highly symmetric icosahedral clusters. The rich chemistry of boron is also dominated by three-dimensional cage structures. Despite its proximity to carbon in the periodic table, elemental boron clusters have been scarcely studied experimentally and their structures and chemical bonding have not been fully elucida...
متن کاملA green chemistry approach for facile synthesis of functionalized boron nitride nanosheets
The lack of a high-yield, renewable and low-cost synthesis method limits the potential applications of boron nitride with impressive characterizations. In this study, a facile method is developed for the preparation of chemically functionalized boron nitride nanosheets (BNNSs) by considering the quantity and quality of chemical materials involved in the synthesis process. The proposed green met...
متن کاملCarborane functionalization of the aromatic network in chemically-synthesized graphene.
The conjugated aromatic system of graphene was used to trap the reactive, boron-rich 1,2-carborane cluster. Functionalization of the graphene surface was confirmed by solid-state MAS (11)B NMR spectroscopy and quantified by X-ray photoelectron spectroscopy. This work represents the first confirmed example of direct functionalization of a graphene lattice with carboranes.
متن کاملA Palladium NCP Pincer Complex as an Efficient Catalyst for Intramolecular Direct Arylation
CH functionalization is a convenient methodology with broad application in total synthesis and medicinal chemistry that provides the same products as already well established cross-coupling methodologies, but with the advantage of avoiding the use of metallic species such as Grignard, boron, silicon and tin compounds. Herein, we report an unprecedented palladium-catalyzed intramolecular direct ...
متن کاملA molecular dynamics study on the impact of defects and functionalization on the Young modulus of boron-nitride nanotubes
In this article, we examine the Young modulus of (6, m) boron-nitride nanotubes with vacancy and functionalization defects. We employ molecular dynamics simulations using the Parrinello-Rahman approach. To this end, all systems are modeled with a reactive many-body bond order Tersoff-potential with parameters due to Matsunaga et al [1], which is able to accurately describe covalent bonding. We ...
