Hexa-peri-hexabenzocoronene decorated with an allenylidene ruthenium complex – almost a flyswatter

A ruthenium allenylidene complex bearing a hexa-peri-hexabenzocoronene (HBC) substituent was synthesised, resembling yet another strategy to decorate HBCs with transition metal fragments.

Intermetallic transfer of unsymmetrical borylene fragments: isolation of the second early-transition-metal terminal borylene complex and other rare species

We report the synthesis of group 6 borylene complexes by the salt elimination method and study their borylene transfer capability to other transition metal fragments, providing new borylene complexes that are inaccessible by other routes.

Coordination chemistry of phosphinocarbynes: phosphorus vs. carbyne site selectivity

The phosphinocarbyne complex [W(CPPh2)(CO)2(Tp*)] (1: Tp* = hydrotris(dimethylpyrazolyl)borate) coordinates transition metal fragments via the phosphine to form bimetallic species [W{CPPh2RhCl2(Cp*)}(CO)2(Tp*)] (2) and [W(CPPh2AuCl)(CO)2(Tp*)] (3).

Ring contraction of metallabenzooxirene to metal carbonyl complexes – a comparative study with the Wolff rearrangement of oxirene and benzooxirene

Transition metal fragments affect the kinetic and thermodynamic feasibility of the Wolff type rearrangement.

Coordination chemistry of oxygen difluoride — an ETS-NOCV analysis

Oxygen difluoride most likely does not form stable complexes with transition metal fragments but initiates formation of halides, oxides, and oxyhalides. This conclusion is drawn as the result of density functional calculations (BP86/TZVP). The interaction between OF2 as potential ligand and the transition metal fragment Cr(CO)5 provides the model scenario. A combined charge and energy decomposition scheme (ETS-NOCV) for bond analysis illustrates the difference in bond behavior between typical donor ligands and oxygen difluoride.
