The search for more efficient processes for the preparation of useful materials is perpetual.Thereby, the design of chemical syntheses that limit waste products is a particularly vibrant field of research, and one class of reactions is near the pinnacle of the low-waste ideal: dehydrocoupling. Dehydrocoupling reactions are a way to create bonds between elements by eliminating only hydrogen gas from the mixture. Although not completely waste-free, the by-product H2 is easily removed, can be used for other purposes and is much lighter than the product molecules. Our preliminary work on applying this concept to the synthesis of dibo-ranes(4), reagents widely used in organic synthesis, led to their catalytic synthesis with high efficiency. This proposal aims to expand these results in order to widen the scope of the reaction to different substrates, to use the new reaction to prepare boron-containing polymers with interesting properties, and to investigate the mechanism of the reaction from a molecular viewpoint.

因此，减少废物的化学合成设计是一个特别有活力的研究领域，其中一类反应接近低废物理想的顶峰：脱氢偶联反应。脱氢偶联反应是一种通过从混合物中仅消除氢气而在元素之间形成键的方法。虽然不是完全无废物，但副产物H2很容易去除，可用于其他目的，并且比产物分子轻得多。我们将这一概念应用于二硼烷（4）的合成，使其催化合成效率提高。该建议旨在扩大这些结果，以扩大反应的范围，以不同的基板，使用新的反应来制备具有有趣的性能的含硼聚合物，并从分子的角度研究反应的机理。
