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

纽约州立大学奥尔巴尼分校化学系Evgeny V.Dikarev博士得到化学部无机、生物无机和有机金属化学项目的支持，旨在开发一种制备含铋和过渡金属的异金属化合物的通用方法。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，这些反应物产生容易分离的挥发性产物。具体目标是混合金属羧酸盐和β-二酮酸盐。异金属桨轮羧酸盐将被开发为催化剂。异金属铋-钯(铂)羧酸盐将被用作制备活性钯和铂催化剂的前体，并在模型反应中进行测试。异金属β-二酮酸酯和氧代二酮酸酯将被组装成潜在的单一来源的前体，用于合成先进的双金属氧化物和氧氟化物材料。众所周知，过渡金属和非金属铋都能催化许多重要的商业过程。该项目旨在制备同时含有过渡金属和铋的化合物。这些催化剂将被评估为可能以协同方式结合过渡金属和铋的性质的催化剂。此外，该项目还为博士后、研究生和本科生提供多才多艺的跨学科和国际培训。

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.
