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)计划共同资助的项目中，印第安纳大学布鲁明顿分校化学系的Dan Mindiola教授将探索环烷烃、直链烷烃和支链烷烃与具有金属-碳多键的瞬时和不饱和钛和钒配合物的脱氢反应。还将研究(I)在基团转移反应中掩蔽和不饱和的钒(I)络合物的化学；以及(Ii)使用大体积芳氧配体(OAR)的低配位和早期过渡金属(主要是钛、钒、铬和Nb)的化学。随着原油等自然资源的减少，需要进行新的化学转化，以环境友好的方式生产合成燃料。拟议研究的一个潜在重要应用是以甲烷和乙烷等挥发性烷烃为基础生产更高级的碳氢化合物(燃料分子)。学生和研究助理将参与合成、催化和动力学研究，所有这些都将为成为一名有竞争力的科学家提供坚实的基础。明迪奥拉教授将通过他与NOBCCHE(全国黑人化学家和化学工程师组织)的IU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).
