CAREER: New Vistas in Early-Transition Metal Complexes Containing Metal-Ligand Multiple Bonds

无机，生物无机和有机化学计划的职业奖支持印第安纳州大学的丹尼尔J. Mindiola教授的工作，以探索具有金属配体多重键的三配位和四配位钛络合物的化学。 本研究包括四配位钛（IV）烷叉、酰亚胺和膦叉配合物的合成、结构、反应性和动力学研究。讨论的主题包括键合的考虑和机制和钛烷叉，酰亚胺和膦系统的反应性研究。 调查扩展到第5组复合物和氧化还原研究源于钒配合物含有金属配体多重键。该项目的具体目标是：i）制备含有金属配体多重键的低配位和高氧化态的前过渡金属配合物。 ii）探索这些独特系统的反应性，并将催化活性与成熟系统进行比较。 iii）将这种合成方法扩展到低配位的第3族和第5族过渡金属的制备。 ㈣通过追溯分析概念图和自我评估技术，招收本科生从事基础科学研究。 ㈤在印第安纳州大学设立两个以学生为基础的分会，招收少数群体进入物理科学。本工作旨在通过探索新的多键过渡金属配合物来开发新的催化剂。 教育计划是培养本科生的研究意识，并实施以学生为基础的章节，以招募本科生（特别是来自代表性不足的群体）进入物理科学。

This CAREER award in the Inorganic, Bioinorganic and Organometallic Chemistry program supports work by Professor Daniel J. Mindiola at Indiana University to explore the chemistry of three- and four-coordinate titanium complexes having metal-ligand multiple bonds. The research involves the synthesis, structure, reactivity, and kinetic studies of a four-coordinate titanium(IV) alkylidene, imide, and phosphinidene complexes. Topics addressed include bonding considerations and mechanistic and reactivity studies of titanium alkylidene, imide, and phosphinidene systems. Investigations extend to group 5 complexes and redox studies stemming from vanadium complexes containing metal-ligand multiple bonds. Specific targets of the project are to: i) Prepare low-coordinate and high-oxidation state early-transition metal complexes containing metal-ligand multiple bonds. ii) Explore the reactivity of these unique systems and compare catalytic activity with well-established systems. iii) Expand this synthetic methodology to the preparation of low-coordinate group 3 and 5 transition metals. iv) Through retro-analytical concept mapping and self-assessment techniques, recruit undergraduate students in basic science-oriented research. v) Implement two student-based chapters at Indiana University for the recruitment of minority groups into the physical sciences. This work aims toward new catalysts by exploring new transition metal complexes with multiple bonds. The education plan is to develop undergraduate research awareness and implementation of student-based chapters for the recruitment of undergraduates (especially from underrepresented groups) into the physical sciences.
