Abstract：The development of human society is inseparable from the discovery and creation of new substances. Synthetic chemistry is one of the most important tools and methods for creating new substances. In the process of the creating new substances， the elements such as phosphorus， fluorine， boron， silicon and rare earth play an essential role. However， the resources of these important elements are depleted rapidly because of the irrational use. Therefore， in the view of the scientific problems of "the creation and transformation of new substances"， the basic and cutting-edge research on the organic chemistry of these elements is highly importance for developing new synthetic chemistry and promoting the efficient use of our element resources， and consequently is beneficial to sustainable development of human society. Based on the long-term and productive studies on the elemento-organic chemistry， particularly on the organic chemistries of aforementioned important elements in China in last few decades， the researches of this project will set up four subjects including （1）New organo-phosphorus reagents and new functions； （2）Selective synthesis of organo-fluorine compounds and their applications； （3）Properties and applications of organo-boron and organo-silicon compounds； （4）Synthesis and properties of new organo-metallic compounds of rare earth elements. This project will intend to in-depth investigate and explore the new bond-forming mode and new reactivity of elemento-organic compounds； to develop new reagents and discover new functions of elemento-organic compounds through regulating their steric and electronic structures； to synthesize new functional organic compounds and materials， and to develop new synthetic methodologies. All of these studies will focus on the scientific issues including （1）new bond-forming mode of element-organic compounds； （2） new reactivity of elemento-organic compounds； （3）new properties of elemento-organic compounds and their regulations. By implementation of this project， the developments of a number of new elemento-organic reagents， new reactions， and new methodologies are expected. This project will also promote the development of organic chemistry and related disciplines in our country. Furthermore， research achievements of this project will provide a scientific basis and technological support for improving the efficiency of the use of element resources and will promote the sustainable development of our society.
