Metathetical Exchange, Synthesis and Carbon Dioxide Addition of Higher Homologues of Group 9 Metal Carbynes

Angewandte Chemie International Edition, Accepted Article.
A one‐pot synthesis for previously unknown heavy homologues of group 9 metal carbynes [(Me3P)3CoºGeAr*] (1), [(Me3P)3RhºGeAr*] (2), [(Me3P)3IrºGeAr*] (3), [(Me3P)3IrºSnAr*] (5), and [(Et3P)3IrºPbAr*] (7) is presented [Ar* = C6H3‐2,6‐(Trip)2, Trip = 2,4,6‐C6H2iPr3]. During these preparations the tetrylidynes [(Me3P)3RhºSnAr*] (4), and [(Me3P)3RhºPbAr*] (

Is Phenylnitrene a Missing Link in the Formation of Polycyclic Aromatic Nitrogen Heterocycles?

Angewandte Chemie International Edition, Accepted Article.
The incorporation of heteroatoms into the framework of polycyclic aromatic hydrocarbons (PAHs), in particular of nitrogen to yield polycyclic aromatic nitrogen heterocycles (PANHs), has been proposed for both astronomical and combustion environments, but no suitable precursors and pathways have been found.

Controlled Growth of Oligophenylene‐Structures on Graphene for Facile Secondary Functionalization

Angewandte Chemie International Edition, EarlyView.
By thermal decomposition of different BPO‐based peroxides with different substituents, dendrimeric oligophenylene structures with thicknesses up to 10 nm have been grown on graphene in a controlled manner. These newly introduced structures provide active sites for further functionalization as they have a higher reactivity than the graphene lattice, as ...

closo‐Carboranyl Analogs of β‐Arylethylamines: Direct Synthesis from Alkenes via EnT‐Catalysis

Angewandte Chemie International Edition, Accepted Article.
closo‐Carboranes are icosahedral carbon‐boron clusters with unique properties and broad applicability. They particularly stand out in the context of drug development as privileged structural motifs for boron neutron capture therapy (BNCT) and as highly hydrophobic bioisosteres for the rotational volume of phenyl rings.
