With support from the Organic Dynamics Program, Dr. Stang will continue to study novel unsaturated species and intermediates and their chemistry. Specific areas of research to be pursued by Dr. Stang include: (i) generation and chemistry of diatomic carbon and ylides derived from diatomic carbon, (ii) mechanism of Ni-Pd-Pt mediated unsaturated cross-couplings and unsaturated carboxylations, (iii) homogeneous C-H bond activation and heterobimetallic complexes, (iv) synthesis and chemistry of highly strained ring systems, and (v) synthesis of (presumably stable) xenon-carbon species. The long-range objectives of Dr. Stang's project, which is concerned with several areas of mechanistic (physical-organic) and organometallic chemistry, include: (i) synthesis, characterization, and studies of various aspects of the chemistry of novel reactive intermediates (e.g., diatomic carbon, unsaturated carbenes), and (ii) fundamental mechanistic studies of such organometallic reactions as vinylic cross-coupling and homogeneous activation of carbon-hydrogen bonds. It is anticipated that this broad and diverse program of fundamental research will provide (i) new mechanistic insight into extensively used modern synthetic reactions and (ii) new routes for synthesizing reactive intermediates in solution.

在有机动力学项目的支持下，斯坦博士将继续研究新的不饱和物种和中间体及其化学。Stang博士将从事的具体研究领域包括：(I)双原子碳和由双原子碳衍生的叶立德的生成和化学，(Ii)Ni-Pd-Pt介导的不饱和交叉偶联和不饱和羧化反应的机理，(Iii)均相C-H键活化和异双金属络合物，(4)高应变环系的合成和化学，以及(5)(可能稳定的)氙碳物种的合成。Stang博士的项目涉及机械(物理-有机)和有机金属化学的几个领域，其长期目标包括：(I)合成、表征和研究新型活性中间体(例如双原子碳、不饱和卡宾)的化学的各个方面，以及(Ii)乙烯交叉偶联和碳氢键均相活化等有机金属反应的基本机理研究。预计这一广泛而多样的基础研究计划将提供(I)对广泛使用的现代合成反应的新的机理见解和(Ii)在溶液中合成活性中间体的新途径。
