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).

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，印第安纳州大学布卢明顿化学系的Dan Mindiola教授将探索环状、直链和支链烷烃与具有金属-碳多重键的瞬时和不饱和钛和钒络合物的脱氢反应。 还需要研究的是（i）掩蔽和不饱和钒（I）配合物在基团转移反应中的化学;和（ii）低配位和早期过渡金属（主要是Ti，V，Cr和Nb）使用大体积芳基氧化物配体（OAr）的化学。 随着原油等自然资源的减少，需要新的化学转化以环境友好的方式生产合成燃料。 这项研究的一个潜在的重要应用是基于甲烷和乙烷等挥发性链烷烃生产高级烃（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。 教授Mindiola将通过他与NOBCChE（黑人化学家和化学工程师的全国组织）的IU章协会与学生代表性不足的群体。
