[TOP] Nature Chemistry: Realizing a Brand-new Aromatic System, Metallapentalyne. (2013-06-23)

Aromaticity, one of the most fundamental concepts in organic chemistry, provides intrinsic stabilisation for cyclic compounds as a result of the delocalisation of π electrons. Currently, aromatic compounds (e.g., benzene, benzene derivatives, porphyrins, fullerenes, carbon nanotubes and graphene) have been applied in almost every field, including chemical engineering, biomedicine, materials science, energy science and environmental science.

Selective Difunctionalization of Unactivated Aliphatic Alkenes Enabled by a Metal–Metallaaromatic Catalytic System(2022-02-09)

We describe a heterometallic [Os-Cu] complex with the characteristics of bimetallics, metallaaromatics, and pincer complexes. This complex serves as a highly effective catalyst for selective amino- and oxyselenation of unactivated alkenes. More than 80 examples including challenging substrates of unsymmetric aliphatic alkenes and amine-based nucleophiles in such reactions are provided.

Nature Communications: Successive Modification of Polydentate Complexes Gives Access to Planar Carbon- and Nitrogen-based Ligands(2019-04-03)

Polydentate complexes containing combinations of nitrogen and carbon (N and C) ligating atoms are among the most fundamental and ubiquitous molecules in coordination chemistry, yet the formation of such complexes with planar high-coordinate N/C sites remains challenging. Herein, we demonstrate an efficient route to access related complexes with tetradentate CCCN and pentadentate CCCCN and NCCCN cores by successive modification of the coordinating atoms in complexes with a CCCC core.

Constraint Of A Ruthenium-Carbon Triple Bond To A Five-Membered Ring(2018-06-22)

The incorporation of a metal-carbon triple bond into a ring system is challenging because of the linear nature of triple bonds. To date, the synthesis of these complexes has been limited to those containing third-row transition metal centers, namely, osmium and rhenium. We report the synthesis and full characterization of the first cyclic metal carbyne complex with a second-row transition metal center, ruthenapentalyne.
