Dinuclear organotin compounds carrying naphthylene- and biphenylene-spacer groups

Dinuclear Organotin Building Blocks and their Conversion into a Tetranuclear Macrocycle Containing Sn−O−Sn Linkages

“…[24,59,[65][66] Interconnection of such organotin tectons through di-or oligotopic ligands such as carboxylates, dithiocarbamates, phosphates, etc., constitutes a pathway to a plethora of metalla-supramolecular assemblies. [65][66] In continuation of previous works, [11,24,59,[65][66][67] herein we report on the formation of two di-nuclear organotin compounds carrying voluminous organic substituents at the metal atoms that were then functionalized with a SnÀ X bond (X = Cl, I). In addition, the potential for the formation of a novel class of tetra-nuclear macrocyclic structures through linkage of the halogenated building blocks by SnÀ OÀ Sn fusion [11,68] was explored.…”
