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.
新型杂棱烷[RSnE]4 的合成为 E = As 成功实现，而对于 E = P 则观察到不同的行为。芳基取代的氯代锡烯与重氰酸盐同系物 PCO- 和 AsCO-的盐反应。与 AsCO-盐的反应主要生成[TerSnAs]4（Ter = 2,6-二甲基苯基）。相比之下，TerSnCl 与 NaPCO 的反应进行得不太干净，得到了混合物产物。主要产物推测为中性[Ter4Sn4P4]化合物，但它不是棱烷。可以通过晶体学方法对该反应的各种副产物进行表征。
