Syntheses and Mechanisms of Ligand Substitution Reactions of Organometallic Complexes

在这个由无机，生物无机， 有机化学计划，西北大学的Fred Basolo 大学将调查影响利率的因素 有机金属化合物中的配体取代。一个伟大 我们需要尽可能多地了解 和定量方面的速度和机制，这些 反应，这是所有均相反应中必不可少的步骤。 使用有机金属化合物作为催化剂的催化循环 催化剂的 该项目将包括合成和详细的动力学和 几个系列的化合物，包括 以下一般类型： 铬、钼和钨;“开放”铬络合物 相同的金属;钴的π-杂原子羰基金属， 铑和铱;早期过渡金属 钒、铌和钽的金属羰基化合物;和 例如钼的二氧化硫络合物。

In this project funded by the Inorganic, Bioinorganic, and Organometallic Chemistry Program, Fred Basolo of Northwestern University will investigate the factors that affect the rates of ligand substitution in organometallic compounds. A great need exists to know as much as possible about the fundamental and quantitative aspects of the rates and mechanisms of these reactions, which are an essential step in all homogeneous catalytic cycles making use of organometallic compounds as catalysts. The project will include the synthesis and detailed kinetic and mechanistic studies of several series of compounds including the following general types: the metal nitrosyl carbonyls of chromium, molybdenum and tungsten; "open" pentadienyl complexes of the same metals; pi-heteroatom metal carbonyls of cobalt, rhodium and iridium; the early transition cyclopentadienyl metal carbonyls of vanadium, niobium and tantalum; and metal sulfur dioxide complexes of, for example, molybdenum.
