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.

来自有机动力学项目的这笔拨款支持了加州理工学院Sita教授的工作，他将提供关于聚锡烷的新实验数据，这些数据可用于测试从头计算水平上关于这些有机分子的14组重原子类似物的结构、稳定性和性质的预测的准确性和可靠性。新型的保护基团将被开发出来，可以与Sn-Sn键形成的氢锡解反应结合使用，用于复杂的聚锡烷结构的程序化构建，包括线性低聚物、支链树状大分子、推进剂、棱柱体和双环结构。在这个项目中，Lawrence R. Sita教授将开发新的和扩展现有的策略来合成线性低聚物、支链树状大分子、螺旋烷、棱柱烷和其他双环聚锡烷结构。目标有机锡化合物具有与轻烃类似物中的碳骨架相同的锡骨架。Sita的研究将通过提供对其范围和局限性的有价值的见解，将有机锡化学推向前沿，这对材料应用和理论见解都很重要。
