With support from the Organic Dynamics Program, Dr. Billups will expand the recently developed vacuum gas solid reaction technique (VGSR) to the synthesis of highly unstable compounds under conditions where structural studies can be performed. Particular emphasis will be placed upon the use of solid alkalai fluoride to effect the elimination of beta-halosilanes to yield highly strained intermediates. In addition, bifunctional cycloproparenes will be polymerized with silver ion to produce a series of new aromatic materials. Finally, the organic and organometallic chemistry of C-60 "Buckminsterfullerene" will be studied. %%% A major focus of Dr. Billups' research program in recent years has been the development of a vacuum gas phase procedure for synthesizing small ring compounds. This approach, which is utilized in only one other laboratory in the United States, allows the reactive species to be isolated at low temperature for subsequent chemical and structural studies. In other work, Dr. Billups will study some aspects of the chemistry of a new allotrope of carbon, "Buckminsterfullerene", which contains a cluster of sixty carbon atoms. This novel, all-carbon cluster is of considerable interest from a theoretical standpoint and also for its potential materials applications.

在有机动力学计划的支持下，比卢普斯博士将把最近开发的真空气固反应技术(VGSR)扩展到在可以进行结构研究的条件下合成高度不稳定的化合物。将特别强调使用固体碱性氟化物来消除β-卤代硅烷，以产生高度紧张的中间体。此外，双官能团环丙烷还将与银离子聚合，合成一系列新型芳香族材料。最后，对C-60“巴克明斯特富勒烯”的有机和有机金属化学进行了研究。%近年来，比卢普斯博士研究计划的一个主要重点是开发一种用于合成小环化合物的真空气相程序。这种方法只在美国的另一个实验室使用，允许在低温下分离活性物种，用于后续的化学和结构研究。在其他工作中，比卢普斯博士将研究一种新的碳同素异形体“巴克明斯特富勒烯”的某些化学方面，它包含60个碳原子。这种新颖的全碳原子簇从理论角度和潜在的材料应用方面都引起了人们的极大兴趣。
