Oxidation of Bis[2,4,6‐tris(trifluoromethyl)phenyl]stannanediyl by Triplet and Complex‐Bound Dioxygen Homogeneous oxygenation of the stannanediyl [2,4,6‐(CF 3 ) 3 C 6 H 2 ] 2 Sn ( 15 ) by molecular triplet oxygen in toluene solution or heterogeneously in the solid state leads to the formation of the cyclotristannoxane 17 . In a pure oxygen matrix 15 does not react either thermally (10–45 K) or photochemically. Upon treatment of 15 with the dioxygen complex (Ph 3 P) 2 Pt(O 2 ) ( 16 ) a stable five‐membered Pt–Sn–O ring 18 is obtained which is a rare example of a covalently linked main group metal‐transition metal heterocycle. The oxygenation products 17 and 18 were characterized by X‐ray structure analyses which revealed the non‐planarity of both heterocycles.
