In this CAREER project funded by the Chemical Catalysis Program of the Chemistry Division, Professor Vlad M. Iluc of the Department of Chemistry at the University of Notre Dame is developing new tools for the selective reaction of hydrogen atoms bonded to common elements such as carbon, oxygen, boron, nitrogen and silicon. In this project, new approaches that involve metal-ligand cooperation are being developed to facilitate chemical transformations under mild conditions. This work is expected to have environmental and societal impact by providing basic knowledge that allows the development of catalytic processes involving water, alcohol, and amines, which are readily available chemical feedstocks. As the educational component of his project, Professor Iluc is developing an outreach program that focuses on mentoring of students from socio-economic groups that are underrepresented in science. The educational program provides educational opportunities for youth at the Bashor Children's Home and promotes their recruitment into science, technology, engineering and mathematics-based careers.The project targets (1) hydrogen transfer from the ligand to the metal and vice versa, which involves a nucleophilic carbene as part of a diphosphine pincer ligand; (2) hemilabile ligands, which incorporate olefins in a pincer architecture, in order to synthesize new untethered carbene nickel and palladium complexes; and (3) transfer of radical character from the supporting ligand to a coordinated substrate. The first class of complexes features nucleophilic carbene palladium complexes that are applied to the hydration, hydroalkoxylation, and hydroamination of olefins and other unsaturated substrates. The second class focuses on nickel and palladium and is applied to carbon (C)- silicon (Si) and C- boron (B) bond forming reactions. Finally, the third class features radical carbene palladium complexes that are applied to C-hydrogen (H) amination reactions with azides and olefin copolymerization reactions. Molecular models based on density functional theory guide these experiments. The educational project includes collaboration with the Bashor Children's Home, in Goshen, Indiana, a non-profit agency that provides help for at-risk children. In addition, the CAREER Award supports summer research activities at the University of Notre Dame. Visiting high school students work closely with graduate and undergraduate chemistry students in science activities related to research in the Iluc group.

在这个由化学系化学催化计划资助的职业项目中，圣母大学化学系的Vlad M.ILUC教授正在开发新的工具，用于与碳、氧、硼、氮和硅等常见元素键合的氢原子的选择性反应。在这个项目中，正在开发涉及金属-配体合作的新方法，以促进在温和条件下的化学转化。这项工作预计将对环境和社会产生影响，因为它提供了允许开发涉及水、酒精和胺的催化过程的基本知识，这些都是容易获得的化学原料。作为他项目的教育组成部分，ILUC教授正在开发一项外展计划，重点是指导那些在科学领域代表性不足的社会经济群体的学生。该教育计划为Bashor儿童之家的年轻人提供教育机会，并促进他们进入科学、技术、工程和基于数学的职业。该项目的目标是(1)氢从配体到金属的转移，反之亦然，这涉及到亲核卡宾作为双膦钳形配体的一部分；(2)半碱基配体，它将烯烃结合在钳形结构中，以合成新的自由卡宾镍和钯配合物；以及(3)将自由基性质从支持配体转移到配位底物。第一类配合物的特点是亲核的卡宾钯配合物，用于烯烃和其他不饱和底物的水合、氢烷氧基化和氢胺化。第二类是镍和钯，用于碳(C)-硅(Si)和碳-硼(B)键的形成反应。最后，第三类以自由基卡宾钯配合物为特征，用于叠氮化合物的C-氢(H)胺化反应和烯烃共聚反应。基于密度泛函理论的分子模型指导着这些实验。该教育项目包括与印第安纳州戈申的Bashor儿童之家合作，这是一家为高危儿童提供帮助的非营利性机构。此外，职业奖还支持圣母大学的暑期研究活动。来访的高中生与化学专业的研究生和本科生密切合作，开展与ILUC小组研究相关的科学活动。
