Abstract

The focus of this work is inspecting the synthesis and comparison of the activities of a catalyst supported on two silicate materials in the epoxidation of 1-octene. The two new catalyst materials were characterized by infrared spectroscopy, elemental analysis, solid-state Si-29 and C-13 nuclear magnetic resonance, scanning electronic microscope (SEM) and analysis of nitrogen. Lastly, the two new catalysts, SilsesqTCA-1(W(CO)(3)I-2)(3)] and Silica-TCA-{[}W(CO)(3)I-2] were tested as catalysts in reactions of epoxidation of 1octene and compared with their analogue not supported {[}W(C0)3I2(thiocarbamide)]. After an extensive literature search, we verified that our work is the first that has reported the immobilization process of {[}W(C0)(3)I-2(NCCH3)(2)] on silsesquioxane and silica gel functionalized with propyl-thiocarbamide groups and their applications as catalysts of reactions of catalytic epoxidation of 1-octene.
