Covalent functionalization of graphene is recently developed from the formation of sp3 hybridized carbon atom (sp3-C) to the sp3 hybridized nitrogen (sp3-N) at the anchoring site. Here, we investigated the electronic structures and transport properties of the zigzag graphene nanoribbons functionalized ...

Since the existence of the sp2&sp3 hybridized carbon and BN, we can expect the existence of sp2&sp3 hybridized B–C–N compounds. In the theoretical side, some sp2&sp3 hybridized BC2N structures with 8-atom diamond structure have been reported by Sun et al.[12] The sp2 hybridization ...
Here we report the regioselective functionalization of olefins with sp3-hybridized organohalides and organozinc reagents using a simple (terpyridine)iron catalyst. Aliphatic groups of various sizes are successfully installed on either olefinic carbon, furnishing a diverse array of products with congested ...
Thesp3d2atomic hybrid orbital set accommodates how many electron domains? Hybridisation: The formation of a covalent bond in an atom by mixing atomic orbitals that results in hybrid orbitals. The hybrid orbitals that are formed can be easily available in that particular atom. The examples...
