This grant from the Organic Dynamics Program supports the work of Professor Sita at the California Institute of Technology who will provide new experimental data on polystannanes that can be used to test the accuracy and reliability of predictions at the ab initio level of theory concerning the structures, stabilities, and properties of these group 14-heavy-atom analogs of organic molecules. New types of protecting groups will be developed that can be used in conjunction with the Sn-Sn bond forming hydrostannolysis reaction for the programmed construction of complex polystannane structures that include linear oligomers, branched dendrimers, propellanes, prismanes, and bicyclic structures. %%% In this project Professor Lawrence R. Sita will develop new and expand current strategies to synthesize linear oligomers, branched dendrimers, propellanes, prismanes, and other bicyclic polystannane structures. The targeted organo-tin compounds have the same tin- framework as the carbon skeletons in the lighter hydrocarbon analogues. Sita's study will catapult organo-tin chemistry to the forefront by providing valuable insight into its scope and limitations that will be important to materials applications and theoretical insight alike.

有机动力学计划的这项赠款支持加利福尼亚理工学院SITA教授的工作，该研究将提供有关聚斯坦纳人的新实验数据，这些数据可用于测试预测的准确性和可靠性。将开发新型的保护组，可以与SN-SN键形成氢体溶解反应一起使用，用于编程的复杂聚氨烷结构，其中包括线性低聚物，分支树枝状聚合物，丙烷，丙烷，prismanes和bicicclic结构。 在该项目中，劳伦斯·R·Sita教授将制定新的并扩展当前策略，以合成线性低聚物，分支树枝状聚合物，丙烷，丙烷和其他双环聚养殖结构。靶向有机锡化合物具有与较轻的烃类似物中的碳骨架相同的锡​​框。 SITA的研究将通过对其范围和局限性提供宝贵的洞察力来弹射有机罐化学，这对材料应用和理论洞察力都至关重要。
