Dr. Gregory L. Hillhouse, Chemistry Department, University of Chicago, is supported by the Inorganic, Bioinorganic, and Organometallic Chemistry Program of the Chemistry Division to develop metal mediated reactions of nitrous oxide and related species. The oxo and imido insertion reactions of nitrous oxide and organoazides will be utilized to synthesize a series of late transition metal hydroxides, alkoxides, and imides. The metal systems will be chosen so that reductive elimination reactions will result in the clean formation of cyclic organic molecules that contain oxygen or nitrogen heteroatoms. Systems will be constructed in which the metal catalyzes these transformations. One of today's greatest chemical challenges is the selective oxidation of organic substrates. A very attractive oxidant is nitrous oxide, a molecule which liberates only nontoxic and environmentally friendly nitrogen gas after it serves as an oxygen transfer agent. Moreover, nitrous oxide is recognized as both a `greenhouse gas` and a stratospheric `ozone depleter`; it would be advantageous to find new uses for this gas, which is now an underutilized biproduct of the chemical industry. In this project metal systems will be designed to activate nitrous oxide toward oxygen atom transfer reactions and metal catalysts will be developed to facilitate these reactions. As a result new uses for nitrous oxide and some related species will be developed.

芝加哥大学化学系的Gregory L. Hillhouse博士得到了化学部的无机，生物无机和有机金属化学计划的支持，以开发一氧化二氮和相关物种的金属介导的反应。一氧化二氮和有机氮化物的氧和imido插入反应将用于合成一系列晚期过渡金属氢氧化物，烷氧化物和酰亚胺。将选择金属系统，以使还原反应将导致含有氧或氮杂原子的循环有机分子的清洁形成。将构建系统催化这些转换的系统。 当今最大的化学挑战之一是有机底物的选择性氧化。一种非常有吸引力的氧化剂是一氧化二氮，它是一种分子，仅在充当氧气转移剂后仅释放无毒和环保的氮气。此外，一氧化二氮被认为是“温室气体”和平流层ozone depleter'。 找到这种天然气的新用途将是有利的，现在这是化学工业的未充分利用的两种用途。在这个项目中，金属系统将旨在激活一氧化二氮向氧原子转移反应，并将开发金属催化剂以促进这些反应。结果，将开发用于一氧化二氮和一些相关物种的新用途。
