Functionalization of Sn/S Clusters with Hetero- and Polyaromatics

We
report a mild and all-purpose method to synthesize several hydrazone-functionalized
homo- and heteroaromatic molecules, as well as the attachment of the
latter to organic functionalized Sn/S clusters. It turned out that the size of
the aromatic system has a great influence on the crystallization tendency
of the products, which were characterized by NMR spectroscopy, mass
spectrometry, and/or single-crystal X-ray diffraction. The last technique
indicates the presence of intramolecular or intermolecular π
stacking of the aromatic rings.
