The Name is 4,4′-Dibromobiphenyl. Through research, I have a further understanding and discovery of 92-86-4.
Four dinuclear organotin halides of composition XnPh(3-n)SnCH2Si(Me)(2)-C12H8-Si(Me)(2)CH2-SnPh(3-n)Xn (X = Cl, I; n = 1, 2) were prepared and combined in 1:1 stoichiometric reactions with potassium 2,5-pyridinedicarboxylate, 3,5-pyridinedicarboxylate, and piperazine bis-dithiocarbamate, respectively. The reactions yielded a total of five [1 + 1] aggregates with either 21- or 22-membered macrocyclic structures that were fully characterized by elemental analysis, mass spectrometry, IR and NMR (H-1, C-13, Si-29, and Sn-119) spectroscopy, and, in three cases, additionally by single-crystal X-ray diffraction analysis. In solution, the macrocycles exhibit conformational and configurational equilibria being fast on the NMR time scale, which, for one of the macrocycles, were closer examined by variable temperature NMR spectroscopy and DFT calculations.
