Catalytic Dehydrocoupling of Group 13-Group 15 Lewis Acid - Base Adducts: Mechanistic Studies & Synthetic Applications

在分子和聚合物结构中操纵碳元素原子的能力非常发达。因此，有机（碳基）分子和聚合物作为一种非常有用的材料而闻名，其应用范围不断扩大。相比之下，基于元素周期表中的其他元素（即无机元素）创建分子和聚合物结构的合成方法通常是相当偶然的，并且范围非常有限。提出的研究旨在让我们进一步理解、发展和利用我们研究小组关于金属催化的脱氢偶联（氢消除）途径到元素（如硼、氮或磷）原子之间的键的最新发现。具体而言，拟议研究的目的如下：为了了解催化反应是如何起作用的，将这种潜在的通用方法的范围扩展到无机元素的其他组合，以制造其他类型的键，以制备具有磷硼骨架的新聚合物，这些聚合物具有低温、阻燃、或氧化稳定材料或作为高性能陶瓷产品的前体，以开发有机化学中的新合成应用，提供一种改进的方法来制备基于氮化硼的管结构，该管结构在显示器中作为场发射体具有潜在的应用

The ability to manipulate atoms of the element carbon in molecular and polymer structures is very well-developed. As a result organic (carbon-based) molecules and polymers are well-known as a remarkably useful materials with an everexpanding range of applications. In contrast, the synthetic methods available to create molecular and polymeric structures based on other elements in the periodic table (i.e. inorganic elements) are often rather haphazard and are of very limited scope.The proposed research aims to allow us to further understand, develop, and exploit recent discoveries in our research group concerning metal-catalyzed dehydrocoupling (hydrogen elimination) routes to bonds between atoms of elements such as boron and nitrogen or phosphorus.Specifically, the aims of the proposed research are the following: to achieve much needed understanding of how the catalytic reactions work to extend the scope of the potentially versatile method to other combinations of inorganic elements to make other types of bonds to prepare of new polymers with phosphorus-boron backbones with potential applications as low temperature, flameretardant, or oxidatively-stable materials or as precursors to high performance ceramics products to develop new synthetic applications in organic chemistry to provide an improved method to prepare tube structures based on boron nitride which have potential applications in displays as field emitters
