H2 addiert reversibel an die Metall-Metall-Bindung von [(BDI)Ga(H)-Zn(tmeda)(thf)][BAr4F] (BDI−=[HC{C(CH3)N(2,6-iPr2-C6H3)}2]−, TMEDA=N,N,N′,N′-Tetramethylethylendiamin, BAr4F−=[B(C6H3-3,5-(CF3)2)4]−). Aufgrund der stabilisierenden Wirkung Lösungsmittelkoordination werden in THF Hydrierungsprodukte [(BDI)GaH2] und [(tmeda)ZnH(thf)][BAr4F] bevorzugt, aber THF-freie Mischungen aus [(tmeda)ZnH(OEt...

The reactivity of the racemic N-heterocyclic stannylene [{MeHCN(tBu)}Sn] (1) with chalcogenide elements O2, S, Se, and Te has been investigated. In case reaction 1 molecular oxygen, cyclic tristannoxane complex [{MeHCN(tBu)}2Sn(μ-O)]3 (3) was isolated characterised. NMR studies (1H, 13C, 119Sn) show formation D3- C2- symmetric assemblies. Te, respectively, yielded cyclo-distannachalcogenide com...

TheMinkowski sum of two setsA,B ∈ IR, denotedA⊕B, is defined as {a+ b | a ∈ A, b ∈ B}. We describe an efficient and robust implementation for the construction of Minkowski sums of polygons in IR using the convolution of the polygon boundaries. This method allows for faster computation of the sum of non-convex polygons in comparison to the widely-used methods for Minkowski-sum computation that d...
