This award in the Chemical Synthesis (SYN) program supports work by Professor Larry G. Sneddon at the University of Pennsylvania to carry out fundamental studies on the development of new general methodologies that enable the high-yield syntheses of technologically important polyborane compounds, polymers and materials. The project's unique approach uses the activating effects of ionic-liquids and/or transition metal catalysts to induce selective polyborane transformations. The project emphasizes both the discovery of new reactions and an elucidation of their fundamental mechanisms and controlling factors so that a rational basis for applying these methods to a wide range of polyboranes and polyborane reactions is achieved. The broader impacts of the proposed work include the development of new methods for enabling the systematic syntheses of functionally-substituted polyboranes, polyborane-metal complexes and poly(organoborane) polymers that have potential applications as medical agents, high temperature polymers, burn rate modifiers, extractants for nuclear wastes, ceramic precursors and weakly coordinating anions.This project strongly impacts the related fields of organometallic chemistry, catalysis, medicinal chemistry, materials science and alternative energy research and thereby provides interdisciplinary training to a diverse group of undergraduate, graduate, and postdoctoral students.

化学合成（SYN）计划中的这一奖项支持了Larry G. Sneddon在宾夕法尼亚大学进行基础研究，开发新的通用方法，使高产量合成技术上重要的聚硼烷化合物，聚合物和材料。 该项目的独特方法使用离子液体和/或过渡金属催化剂的活化作用来诱导选择性的聚硼烷转化。 该项目强调新反应的发现和阐明其基本机制和控制因素，以便为将这些方法应用于广泛的聚硼烷和聚硼烷反应提供合理的基础。 拟议工作的更广泛影响包括开发新方法，用于系统合成功能取代的聚硼烷，聚硼烷金属络合物和聚（有机硼烷）聚合物作为医药试剂、高温聚合物、燃烧速率调节剂、核废料萃取剂、陶瓷前驱体和弱配位阴离子具有潜在的应用。该项目强烈影响了有机金属化学的相关领域，催化，药物化学，材料科学和替代能源研究，从而提供跨学科的培训，以本科生，研究生和博士后的学生多样化的群体。
