With this renewal award the Organic and Macromolecular Chemistry Program continues its support for the work of Dr. William E. Billups in the Department of Chemistry of William Marsh Rice University in Houston. The work will include the synthesis of new elusive compounds, using a vacuum gas-solid reaction method developed by Dr. Billups to prepare small ring alkenes and bicycloalkenes from beta-halocyclopropylsilanes. Aromatic compounds to be prepared will include cycloproparenes, fullerenes, buckytubes, and functionalized fluorinated single-wall nanotubes. Low temperature reactions of Os atoms with ethylene oxide and of Rh atoms with diazomethane will be carried out to complete studies of low temperature reactions of metal atoms with organic molecules. Structures of gas hydrates will be determined by low-temperature x-ray crystallography. Dr. Billups' research covers a wide variety of areas in physical organic chemistry, including the synthesis and properties of small ring alkenes and bicycloalkenes, fullerenes, fluorinated single-wall carbon nanotubes, and products formed from the reactions of transition metal atoms and small organic molecules at low temperatures. Work will be initiated on the nucleation, growth, and structures of methane hydrates, with the goal of finding inhibitors for their formation. These hydrates can cause serious problems in long distance natural gas pipelines.

有了这个更新奖的有机和高分子化学计划继续支持博士威廉E。比卢普斯在休斯顿威廉马什赖斯大学化学系。 这项工作将包括合成新的难以捉摸的化合物，使用比卢普斯博士开发的真空气固反应方法，从β-卤代环丙基硅烷制备小环烯烃和双环烯烃。 待制备的芳香族化合物将包括环丙烯、富勒烯、巴基管和官能化的氟化单壁纳米管。 将进行Os原子与环氧乙烷和Rh原子与重氮甲烷的低温反应，以完成金属原子与有机分子的低温反应研究。 天然气水合物的结构将由低温x射线晶体学确定。 比卢普斯博士的研究涵盖了物理有机化学的各种领域，包括小环烯烃和双环烯烃，富勒烯，氟化单壁碳纳米管的合成和性质，以及过渡金属原子和小有机分子在低温下反应形成的产物。 将开始研究甲烷水合物的成核、生长和结构，目标是寻找其形成的抑制剂。 这些水合物会在长距离天然气管道中引起严重的问题。
