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

操纵分子和聚合物结构中碳元素原子的能力是非常发达的。因此，有机(碳基)分子和聚合物作为一种非常有用的材料而广为人知，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)来创建分子和聚合物结构的现有合成方法往往相当随意，范围非常有限。拟议的研究旨在使我们能够进一步了解、开发和利用我们课题组关于金属催化脱氢偶联(氢消除)途径到元素原子之间的键的最新发现，例如硼和氮或磷。建议的研究目标如下：为了达到对催化反应如何工作的迫切需要的了解，将潜在的通用方法的范围扩展到其他无机元素的组合，以使其他类型的键来制备具有潜在应用的新型聚合物，这些聚合物具有潜在的应用，如低温、阻燃剂或氧化稳定材料，或作为高性能陶瓷产品的前驱体开发在有机化学中的新的合成应用，以提供一种改进的方法来制备基于氮化硼的管状结构，该管结构在显示器中具有潜在的场发射应用

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
