Photo-dimers of 1,5-diethynylanthracene and 1,5-bis[(trimethylsilyl)ethynyl]anthracene, obtained by UV radiation of the monomers, were treated with the bulky aluminium hydride [(SiMe3)2HC]2AlH in hydroalumination reactions. Hydroalumination of the tetraethynyl-substituted anthracene photo-dimers (syn...

Equimolar mixtures of pyridine (Py) with para-halotetrafluoro-pyridine (BrTFP and ITFP) were investigated by VT-diffusion NMR experiments. The formation of a halogen-bond-stabilized ITFP·Py complex was de¬tected upon cooling a solution in...

Starting with 1,2 dibromobenzene and 1,2,3,4 tetrafluorobenzene, dimethyl(2-(trimethylstannyl)phenyl)phosphane, Me2P(o-C6H4)SnMe2, and dimethyl-[2,3,4,5-tetrafluoro 6 (trimethylstannyl)phenyl]phosphane, Me3P(o-C6F4)SnMe3, were synthesized and used in tin-gold exchange reactions to prepare two gold(I) dimers, bis[(2 dimethylphosphino)phenyl]di-gold(I), [Au2(μ2-C6H4PMe2)2],...

The molecular structure of acenaphthene has been determined experimentally in the gas phase using gas electron diffraction intensities and literature-available rotational constants. Supplementary highlevel quantum-chemical calculations were utilized in refinements...

Three bifunctional boron‐Lewis acids based on a 1,2‐diethynylbenzene backbone were synthesized using a tin‐boron exchange protocol in good to very good yields. Complexation experiments with pyrimidine were thoroughly investigated using the example of 1,2‐bis(benzo[d][1,3,2]dioxaborol‐2‐ylethynyl)benzene (3) in solution, in the solid phase and by quantum‐chemical calculations. Two adducts were structurally investigated by X‐ray diffraction experiments. DOSY‐/VT‐NMR experiments gave insight into the dynamic behaviour of the synthesized poly‐Lewis acids with pyrimidine.
