Metal-Ligand Multiple Bonds and Their Role in Alkane Metathesis, Dehydrogenation and Group-Transfer Chemistry

在这个由化学系化学合成（SYN）和化学催化（CAT）项目共同资助的项目中，印第安纳大学布卢明顿分校化学系的Dan Mindiola教授将探索具有金属-碳多重键的瞬态和不饱和钛和钒配合物的环状、线性和支链烷烃脱氢反应。还需要研究的是(i)掩膜和不饱和钒(i)配合物在基团转移反应中的化学性质；（ii）低配位和早期过渡金属（主要是Ti， V， Cr和Nb）的化学性质，使用大块的芳基氧化物配体（OAr）。随着原油等自然资源的减少，需要新的化学转化以环保的方式生产合成燃料。这项拟议研究的一个潜在重要应用是生产基于挥发性石蜡（如甲烷和乙烷）的高级碳氢化合物（燃料分子）。学生和研究人员将参与合成、催化和动力学研究，为成为一名有竞争力的科学家提供坚实的基础。Mindiola教授将通过他与NOBCChE（全国黑人化学家和化学工程师组织）印第安纳大学分会的联系，与来自代表性不足群体的学生合作。

In this project co-funded by the Chemical Synthesis (SYN) and Chemical Catalysis (CAT) programs of the Chemistry Division, Professor Dan Mindiola of the Department of Chemistry of the Indiana University - Bloomington will explore dehydrogenation reactions of cyclic, linear, and branched alkanes with transient and unsaturated titanium and vanadium complexes having metal-carbon multiple bonds. Also to be studied are (i) the chemistry of a masked and unsaturated vanadium(I) complex in group-transfer reactions; and (ii) the chemistry of low-coordinate and early-transition metals (mainly Ti, V, Cr, and Nb) using a bulky aryl oxide ligand (OAr). As natural resources such as crude oil dwindle, novel chemical transformations are needed to produce synthetic fuels in a environmentally friendly manner. A potentially important application of the proposed research is to produce higher hydrocarbons (fuel molecules) based on the volatile paraffins such as methane and ethane. Students and research associates will be involved in synthesis, catalysis and kinetics study all in combination to provide a strong foundation to become a competitive scientist. Professor Mindiola will be working with students from underrepresented groups through his association with the IU chapter of the NOBCChE (National Organization of Black Chemists and Chemical Engineers).
