Fourier transform infrared spectrometer

鉴于目前强调可持续性和有效利用自然资源（包括石油衍生碳氢化合物），开发新型高活性催化剂的机会很大，这些催化剂能够提高现有化学过程的效率，或者可以提供更少浪费的全新合成方案。特别是过渡金属催化剂已经上升到为现代合成化学的许多问题提供解决方案的挑战，因此，催化的大多数突破都植根于过渡金属反应性的基础研究。在这种情况下，Turculet小组的研究目标是制备过渡金属配合物，这些配合物由于其独特的结构而表现出新的和/或改进的反应性。Turculet小组专门针对以阴离子为主基团元素给体（如Si， P）为特征的过渡金属钳形配合物的新家族，并成功地证明了这种类型的配合物在催化（如酮的转移氢化）中具有活性，并且具有高活性，这表明它们能够在温和条件下选择性地切割碳氢化合物和胺的C-H和N-H键。这些配合物的表征和结构阐明在本研究中起着至关重要的作用，因为它允许结构-活性分析，并有助于合理设计靶向化学转化的催化剂。所要求的傅里叶变换红外光谱仪（FT-IR）将被包括Turculet小组在内的达尔豪斯大学化学系的合成化学研究人员持续使用，作为表征和结构分配新的有机，无机和过渡金属化合物的关键工具。该仪器将提供关键数据，使研究人员能够拼凑出对新分子和材料的结构和组成的理解，从而促进识别有效的新策略，以应对合成挑战。

Given the current emphasis on sustainability and the effective use of natural resources (including petroleum-derived hydrocarbons), significant opportunities exist for developing new types of highly reactive catalysts that are able to improve the efficiency of existing chemical processes, or that can provide access to entirely new synthetic protocols that are less wasteful. Transition metal catalysts in particular have risen to the challenge of providing solutions for many of the problems of modern synthetic chemistry, and as such, most breakthroughs in catalysis are rooted in the fundamental study of transition metal reactivity. In this context, research in the Turculet group targets the preparation of transition metal complexes that exhibit new and/or improved reactivity properties by virtue of their unique construction. The Turculet group is specifically targeting new families of transition metal pincer complexes that feature formally anionic heavier main group element donors (e.g. Si, P), and has successfully shown that complexes of this type are active in catalysis (e.g. transfer hydrogenation of ketones) and are highly reactive, as indicated by their ability to selectively cleave the C-H and N-H bonds of hydrocarbons and amines (respectively) under mild conditions. The characterization and structural elucidation of such complexes plays a crucial role in this research, as it allows for structure-activity analysis and facilitates the rational design of catalysts for targeted chemical transformations. The requested Fourier Transform Infrared (FT-IR) spectrometer will be employed on a continual basis by synthetic chemistry researchers, including the Turculet group, in the Department of Chemistry at Dalhousie University as a key instrument for the characterization and structural assignment of new organic, inorganic, and transition metal-containing compounds. This instrumentation will provide crucial data that will enable researchers to piece together an understanding of the structure and composition of new molecules and materials, thereby facilitating the identification of effective new strategies for meeting synthetic challenges.
