研究的重点是五个方面。 研究将 进行了新的单原子的合成和化学 环桥芳烃及其衍生物;产物， 五配位立体化学及其机理 α-卤代烷基硅烷与 将探测亲核试剂;将使用新试剂和方法 开发用于产生重氮化合物，它们的卡宾和 后续产品;将进行研究，以更好地 了解卡宾中的空间效应和电效应 重氮金属的重排过程和化学 化合物和双卡宾。 有了这个更新奖，合成有机计划是 支持哈罗德·谢克特博士的研究， 俄亥俄州州立大学化学系。 教授 Shechter将探索各种新颖的结构类型， 化学反应。 这些包括五配位硅 化合物、应变桥芳烃和不寻常的类卡宾 化合物和前体。

The focus of the research is five-fold. Studies will be conducted on the synthesis and chemistry of novel single-atom peri-bridged arenes and their derivatives; the products, stereochemistry and mechanisms of pentacoordinate addition-rearrangement-reactions of alpha-haloalkylsilanes with nucleophiles will be probed; new reagents and methods will be developed for generating diazo compounds, their carbenes and subsequent products; studies will be carried out to better understand steric and electrical effects in carbenic reaarangement processes and the chemistry of metallodiazo compounds and metallocarbenes. With this renewal award, the Synthetic Organic Program is supporting the research of Dr. Harold Shechter of the Department of Chemistry at Ohio State University. Professor Shechter will probe a variety of novel structure types and chemical reactions. These include pentacoordinate silicon compounds, strained-bridged aromatics, and unusual carbenoid compounds and precursors.
