Oxometal Complexes and Hydrocarbon Functionalization

9412465希尔埃默里大学博士克雷格A.希尔，化学系，埃默里大学，是由化学部的无机，生物无机和有机化学计划的支持，研究到杂多酸盐（HPOM）作为均相催化剂的发展。将开发氧化物从HPOM转移到烷烃的方法，因为它对任何涉及氧化官能化的过程都至关重要。将评估影响HPOM催化氧化使用环境有利的过氧化氢的因素。由于催化剂通常具有有限的寿命，因此将寻求新的系统，该系统将修复在它们操作时在它们中出现的缺陷。最后，将确定HPOM诱导非常不活泼的材料如金刚石表面的反应和催化氧化硫化氢的能力。 氧化反应在化学的许多领域中是非常常见和重要的。在工业规模上，它们经常受到环境问题的困扰，因为它们使用或生产有毒的、可能造成污染的物质。在该项目中，将开发一类新的环境友好型催化剂。将评估它们发挥作用的基本方式，这些知识将用于设计非常不活泼的材料的氧化过程和有毒硫化氢转化为硫的过程。

9412465 Hill Emory University Dr. Craig A. Hill, Chemistry Department, Emory University, is supported by the Inorganic, Bioinorganic, and Organometallic Chemistry Program of the Chemistry Division for research into the development of heteropolyoxometallates (HPOM) as homogeneous catalysts. The transfer of oxide from an HPOM to alkanes will be developed because of its central importance to any process which involves oxidative functionalization. The factors which influence HPOM catalyzed oxidation using the environmentally advantageous hydrogen peroxide will be evaluated. As catalysts normally have a finite lifetime, new systems will be sought which will heal defects which occur in them as they operate. Finally, the ability of HPOM's to induce reactions of very unreactive materials such as diamond surfaces and to catalytically oxidize hydrogen sulfide will be determined. Oxidation reactions are very common and important in many areas of chemistry. On the industrial scale they are often plagued by environmental problems because they either use or produce toxic, potentially polluting substances. In this project a new class of environmentally benign catalysts will be developed. The basic way in which they function will be assessed and this knowledge will be used to design processes for oxidations of very non-reactive materials and for the conversion of toxic hydrogen sulfide into sulfur.
