Organometallic Transformations in Acid Media

怀俄明大学化学系迪恩·M·罗迪克博士受到化学部无机、生物无机和有机金属计划的支持，研究氟烷基膦过渡金属络合物在酸性和超强酸介质中的有机金属化学。将开发新的含有弱配位阴离子的新型阳离子氟烷基膦金属络合物和类似的中性d8金属络合物的制备路线。利用这些化合物的清单，将概述酸介导的金属有机化学的一般领域。首先，将在酸性条件下考察官能化烯烃的二聚化、质子诱导的羰基插入、乙烯/CO共聚和酸定向烷烃官能化。根据这部分项目的结果，化学将扩展到溶液和固体超强酸介质。许多重要的化学反应是在酸性条件下进行的。然而，金属有机化合物是重要的实验室和商业催化剂和试剂，在酸性环境中往往不稳定。该项目的目标是一类新发现的对酸性环境具有显著耐受性的有机金属化合物，旨在开发能够在酸性和超强酸介质中促进各种反应的新型金属催化剂。

Dr. Dean M. Roddick, Department of Chemistry, University of Wyoming, is supported by the Inorganic, Bioinorganic, and Organometallic Program of the Chemistry Division for the study of the organometallic chemistry of fluoroalkylphosphine transition metal complexes in acid and superacid media. Preparative routes will be developed for new cationic fluoroalkylphosphine-group 10 metal complexes, which incorporate weakly coordinating anions, and for analogous neutral d8 metal complexes. Using this inventory of compounds the general area of acid-mediated organometallic chemistry will be outlined. Initially, the dimerization of functionalized olefins, proton induced carbonyl insertion, ethylene/CO copolymerization, and acid directed alkane functionalization will be examined in acidic situations. Based on the results of this portion of the project, the chemistry will be extended to solution and solid superacid media. Many important chemical reactions are carried out under acidic conditions. However, organometallic compounds, which are important laboratory and commercial catalysts and reagents, often are not stable in acidic environments. This project targets a newly discovered class of organometallic compounds that have remarkable tolerance for acidic surroundings and aims at developing new types of metal catalysts that can promote a variety of reactions in acid and superacid media.
