在当代有机合成中，有机磷试剂在有机新反应、新试剂与新方法的研究中扮演着非常重要的角色，有机合成上的许多突破都与新的有机磷试剂或磷配体的发现密切相关。同时，有机磷试剂在生命科学、药物化学和材料化学当中也有着广泛的应用。因此，发展简洁、高效的碳-磷键构建的新反应、新方法一直是化学家们研究的热点和挑战之一。在过去的三年中，我们在过渡金属催化的C-P键构建反应研究中取得了一些可喜的进展，对过渡金属催化的C-P键构建反应机制积累了一些新的认识和理解。在此基础上，我们希望对过渡金属催化的脱氢偶联反应构建C-P键的研究进行系统而深入的研究，利用膦氧氢试剂作为亲电试剂或采用直接脱除氢气的策略，发展一些更加简捷、高效，高选择性的符合绿色化学发展的新反应、新方法，并应用到功能性有机磷化合物和有机磷新试剂的合成当中。促进有机磷化学的创新和发展。

In modern organic synthesis,organophosphrous reagents play the very important role in organic new reactions,new reagents and new methodologies. Many breakthrough about the organic synthesis are germane to the new phosphrous reagents and ligands.Moreover,organophosphrous reagents also have been applied in life science, pharmacochemistry and materials chemistry extensilvely. Thus, the development of simplest, higher efficient new reactions and methods for the C-P bond formation is one of the research hotspots and challenges of chemists.In past three years, we have made some exciting progress in C-P bond formation and accumulated some new insight and understanding of transition metal catalyzed C-P bond construction. Based on these advancements, we wished to carry out the research of transition metal-catalyzed dehydrogenative cross-coupling reactions to build new C-P bond by using the phosphine oxide as electronic reagents and the novel strategy of direct removal of Hygrogen, and dveloped some more simplier, higher efficacious and best selectivity new reactions and methods for the C-P bond construction, which are harmony with green chemistry, and applied to the synthesis of new functional phosphrous compounds and new phosphrous reagents. These new discoveries will prompt the phosphrous chemistry innovations and developments powerful.
