The Chemical Catalysis Program of the NSF Division of Chemistry supports the research efforts of Professor Adam S. Veige of the University of Florida to explore the use of trianionic pincer-supported transition metal catalysts for the production of value-added materials. This research is conducted in three parts. The first objective is to develop tungsten and molybdenum complexes using unique three-coordinated pincer ligands for alkyne metathesis - an organic reaction involving the redistribution of alkyne (triple) bonds. The trianionic ligand fuses three negatively-charged (anionic) donor groups to the meridional coordination plane, thus enabling access to highly-reactive, coordinatively and electronically unsaturated metal complexes. The second objective capitalizes on the preliminary discovery of highly-active substituted alkyne polymerization catalysts. Experiments elucidate the catalyst's role in the polymerization reaction, providing insight into the creation of new, more active versions of the catalyst. The third objective includes the development of catalysts capable of converting polyolefin waste into usable products. This project focuses on elucidating the rare, but fundamental beta-alkyl elimination reaction. In 2010, the global demand for catalyst manufacturing reached $30 billion. These catalysts produced more than $10 trillion in goods and services annually. Catalyst development, such as that explored in this research project, broadens scientific knowledge and presents opportunities for discovering new catalysts and catalytic reactions. The underlying theme is to transform commodity or feedstock reagents into high-value products using non-precious metals to speed-up the reactions. Student scientists in the Veige research group receive hands-on training in modern inorganic/organometallic chemistry to meet the demands of an increasingly specialized technological workplace. In addition, interactive and entertaining events such as the Chemistry Day at the Oaks Mall are designed to raise public awareness and to inspire the next generation of scientists and their parents.

美国国家科学基金会化学部的化学催化项目支持佛罗里达大学的Adam S. Veige教授的研究工作，以探索使用三阴离子夹子支撑的过渡金属催化剂来生产增值材料。本研究分为三个部分。第一个目标是利用独特的三配位钳形配体开发钨和钼配合物，用于炔复分解-一种涉及炔（三）键重新分配的有机反应。三阴离子配体将三个带负电荷的（阴离子）给体基团融合到子午配位面上，从而可以获得高活性、配位和电子不饱和的金属配合物。第二个目标是利用高活性取代炔聚合催化剂的初步发现。实验阐明了催化剂在聚合反应中的作用，为创造新的、更活跃的催化剂版本提供了见解。第三个目标包括开发能够将聚烯烃废料转化为可用产品的催化剂。这个项目的重点是阐明罕见的，但基本的-烷基消除反应。2010年，全球对催化剂制造的需求达到300亿美元。这些催化剂每年产生超过10万亿美元的商品和服务。催化剂的发展，如本研究项目所探索的，拓宽了科学知识，并为发现新的催化剂和催化反应提供了机会。潜在的主题是将商品或原料试剂转化为使用非贵金属加速反应的高价值产品。维格研究小组的学生科学家接受现代无机/有机金属化学的实践培训，以满足日益专业化的技术工作场所的需求。此外，互动和娱乐活动，如奥克斯购物中心的化学日，旨在提高公众意识，激励下一代科学家和他们的父母。
