Mixing Bismuth with Transition Metals at the Molecular Level: Heterometallic Catalysts, Catalytic and Single-Source Precursors

Evgeny V. Dikarev博士，纽约州立大学奥尔巴尼分校化学系，得到化学系无机、生物无机和有机化学项目的支持，开发了制备含铋和过渡金属的异金属化合物的一般方法。将探索一种基于配位不饱和反应物的低温固相反应的合成方法，该方法产生易于分离的挥发性产物。具体目标是混合金属羧酸盐和β-二酮盐。将开发异金属叶轮羧酸盐作为催化剂。异金属铋钯（铂）羧酸盐将探索作为前体的活化钯和铂催化剂的制备进行测试的模型反应。异金属β-二酮化合物和氧代二酮化合物将作为潜在的单源前体进行组装，用于合成高级氧化物和氟氧化物材料。过渡金属和非金属铋都已知催化许多商业上重要的过程。该项目旨在制备既包含过渡金属又包含铋的化合物。这些将被评价为可以以协同方式将过渡金属和铋的性质联合收割机组合的催化剂。此外，该项目还为博士后，研究生和本科生提供多学科和国际培训。

Dr. Evgeny V. Dikarev, Chemistry Department, SUNY at Albany, is supported by the Inorganic, Bioinorganic and Organometallic Chemistry Program of the Chemistry Division for the development of a general approach for the preparation of heterometallic compounds incorporating bismuth and transition metals. A synthetic method based on low-temperature solid-state reactions of coordinatively unsaturated reactants that yield easily separated volatile products will be explored. Specific targets are mixed-metal carboxylates and beta-diketonates. Heterometallic paddlewheel carboxylates will be developed for application as catalysts. Heterometallic Bi-Pd(Pt) carboxylates will be explored as precursors for the preparation of activated palladium and platinum catalysts to be tested in model reactions. Heterometallic beta-diketonates and oxo-diketonates will be assembled as potential single-source precursors for the synthesis of advanced bimetallic oxide and oxofluoride materials. Both transition metals and the non-metal, bismuth, are known to catalyze a number of commercially important processes. This project aims at preparing compounds that incorporate both a transition metal and bismuth. These will be evaluated as catalysts that may combine the properties of both the transition metal and bismuth in a synergistic fashion. Additionally, the project offer a versatile interdisciplinary and international training for postdoctoral, graduate, and undergraduate students.
