The heterocubane [TerSnAs]4
The synthesis of a novel heterocubane [RSnE]4 was successful for E = As, while for E = P differing behaviour was observed.

| Resumo: | The synthesis of a novel heterocubane [RSnE]4 was successful for E = As, while for E = P differing behaviour was observed. Aryl-substituted chlorostannylenes were treated with salts of heavy cyanate homologues PCO− and AsCO−. The reaction with AsCO− salts afforded primarily [TerSnAs]4 (Ter = 2,6-dimesitylphenyl). In contrast, the reaction of TerSnCl with NaPCO proceeded considerably less cleanly affording a mixture of products. The main product was putatively a neutral [Ter4Sn4P4] compound, however, it is not a cubane. A variety of by-products of this reaction could be characterised crystallographically. |
