The key element of the project is to develop a series of new, main group element based catalysts for the dehydrogenation/dehydrocoupling of phosphine-boranes. This is a virtually unexplored area with only one brief, previous report in 2003 by Denis and coworkers of the use of B(C6F5)3 as a catalyst. The focus will be on low valent compounds of heavy group 14 elements, such as different silylenes, germylenes and stannylenes. Their reactivity and the potential mechanism will be studied by both spectroscopic (e.g. NMR) and theoretical methods (DFT calculations). The work has the potential to open up an important new area at the interface of inorganic and polymer chemistry and the results obtained may be transferable in the future to other main group substrates such as phosphine-alanes and related species. The work will make a significant contribution to the rapidly growing field of catalysis with main group elements.

该项目的核心内容是开发一系列新型的主族元素基膦硼烷脱氢/脱氢偶联催化剂。这是一个几乎未探索的领域，只有一个简短的，以前的报告，在2003年由丹尼斯和同事使用B（C6 F5）3作为催化剂。重点将放在重族14元素的低价化合物，如不同的甲硅烷基，甲锗烷基和甲锡烷基。它们的反应性和潜在的机制将通过光谱（例如NMR）和理论方法（DFT计算）进行研究。这项工作有可能在无机和聚合物化学的界面上开辟一个重要的新领域，所获得的结果可能在未来转移到其他主族底物，如膦铝烷和相关物种。这一工作将对迅速发展的主族元素催化领域做出重要贡献。
