  Synthesis of the first-membered ring compound containing three tin atoms and one oxygen. The crystal structure of the species [O{Sn(C6H3Et2-2,6)2}3]

  摘要：

  Aerial oxidation of the novel homocyclic tetratin species [{SnAr2}3SnArBr] (1) [1] (Ar = C6H3Et2-2,6) affords the tritin heterocycle [O{Sn(C6H3Et2-2,6)2}3] (2), which has been crystallographically characterised; 2 is the first reported oxatristannacyclobutane, and the first heterocyclic tin species having both tin-tin and tin-heteroatom bonds.

  Synthesis, structure and reactivity of the novel tetratin species bromoheptakis(2,6-diethylphenyl)-cyclotetrastannabutane

  摘要：

  Metallation of ArBr (Ar = 2,6-diethylphenyl) with Li power in diethyl ether, followed by addition of stannous chloride at low temperature does not give the expected oligomeric diarylstannane but an essentially quantitative yield of the novel tetrastannabutane [{SnAr2}3SnArBr]. Some reactions of the new species are reported.
