Metal-Catalyzed Diene and Olefin Polymerizations: Mechanistic Studies and Catalyst Design

金属催化二烯和烯烃聚合:机理研究和催化剂设计

基本信息

项目摘要

This award in the Inorganic, Bioinorganic and Organometallic Chemistry Program supports research by Dr. Maurice Brookhart at the University of North Carolina at Chapel Hill to examine the mechanism of diene polymerization reactions by using naked allyl-Ni species and (diene)Ni(allyl)+ species. Both species are highly reactive at low temperature and are key intermediates in diene polymerizations. These Ni "ligandless" complexes along with monoligated complexes and Pd analogs will be used to polymerize butadiene and a series of substituted dienes and to fully elucidate the mechanistic details of these polymerizations so as to identify factors that allow control of the polydiene microstuctures. Living polymerizations will be sought in order to generate a series of copolymers incorporating functional groups with potential new structures and properties. The reactivity of these unique naked M(allyl)+ species will also be explored with other unsaturated molecules including olefins, strained cyclic olefins and alkynes. Other projects include (a) developing a direct synthesis of alkyl aldehydes through combining ethylene oligomerization with an oxidative chain transfer process using N2O and (b) a collaborative project with R. Broene of Bowdoin College to develop catalysts for dimerization of alpha-olefins to the linear alpha-olefin dimers. Through a long-established collaboration with DuPont, recent discoveries from this laboratory on new polymerization catalysts are being brought towards commercialization. Undergraduate students from underrepresented minorities in science will be brought into the research. Graduate students involved in the project are also actively involved in outreach to high schools through the UNC-sponsored "Saturday Academy".
无机、生物无机和有机化学项目的这一奖项支持了查佩尔山的北卡罗来纳州大学的Maurice Brookhart博士的研究,该研究通过使用裸烯丙基-Ni物种和(二烯)Ni(烯丙基)+物种来研究二烯聚合反应的机理。 这两种物质在低温下都具有高度反应性,并且是二烯聚合中的关键中间体。 这些Ni“无配体”配合物沿着单配体配合物和Pd类似物一起将被用于取代丁二烯和一系列取代的二烯,并充分阐明这些聚合的机理细节,以便确定允许控制聚二烯微观结构的因素。 将寻求活性聚合,以产生一系列包含具有潜在新结构和性能的官能团的共聚物。这些独特的裸M(烯丙基)+物种的反应性也将探索与其他不饱和分子,包括烯烃,应变环烯烃和炔。 其他项目包括(a)通过将乙烯低聚与使用N2 O的氧化链转移过程相结合来开发烷基醛的直接合成,以及(B)与R. Bowdoin College的Broene开发用于α-烯烃二聚成线性α-烯烃二聚物的催化剂。通过与杜邦公司的长期合作,该实验室最近发现的新型聚合催化剂正在走向商业化。 来自科学界代表性不足的少数民族的本科生将被纳入研究。 参与该项目的研究生还通过联合国大学赞助的“星期六学院”积极参与向高中的外联活动。
