Spectroscopic and Synthetic Aspects of Alkynes as pi-Base Ligands

该奖项在无机、生物无机和有机金属项目中提供了对有机金属化学研究的支持。Richard S. Herrick和Ronald M. jarrett，圣十字学院化学系。他们将进行一些涉及钼钨二硫代氨基甲酸酯的四种电子供体炔配合物的项目。新的合成方法将用于包含四种配体的配合物：双炔、苯、磷酸炔和氧炔。这些化合物将主要通过核磁共振技术进行表征，并特别注意取代基对C-C键的影响。含有与碳-碳多键相关的过渡金属的化合物因其与催化过程的相关性而被研究。在这个基础研究项目中，将在不同的电子环境中制备和表征含有这种类型键的化合物。这项工作将由本科生进行，一些高中教师和学生也将参与其中。因此，这项工作预计将产生科学和教育两方面的影响。

This award in the Inorganic, Bioinorganic, and Organometallic Program provides support for an investigation in organometallic chemistry by Drs. Richard S. Herrick and Ronald M. Jarret, Chemistry Department, Holy Cross College. They will carry out a number of projects involving four electron donor alkyne complexes of molybdenum and tungsten bis(dithiocarbamates). New synthetic methods will be developed for complexes containing four types of ligands: bis(alkynes), benzynes, phosphaalkynes, and oxo alkynes. The compounds will be characterized primarily by NMR techniques, and particular attention will be paid to the effect of substituents on the C-C bond. %%% Compounds which contain transition metals associated with carbon-carbon multiple bonds are studied because of their relevance to catalytic processes. In this fundamental research project, compounds containing bonds of this type in differect electronic environments will be prepared and characterized. The work will be carried out by undergraduate students, and some high school teachers and students will also be involved. Thus the work is expected to have both scientific and educational impact.
