Benzimidazole-functionalized dendrons as molybdenum supports for selective epoxidation catalysis

Role of Polymer Structures in Catalysis by Transition Metal and Metal Oxide Nanoparticle Composites

“…The catalyst was studied in epoxidation of alkenes and oxidation of sulfides and sulfoxides. Although the authors claimed a great catalytic activity of the catalyst in the model reaction of epoxidation of cis -cyclooctene under optimized conditions, no evidence of the advancement of this catalyst over reported earlier molybdenum-based catalysts has been found. − …”

Investigation of a molybdenum-containing silica catalyst synthesized by the sol–gel process in heterogeneous catalytic esterification reactions using methanol and ethanol

“…Molybdenum oxides were immobilized on different supports like benzimidazole-functionalized dendrons [14], alumina [15,16], titania [17], zirconia [18], and silica [19,20], for use as catalyst in different process; e.g., catalytic oxidation of ethanol with air, esterification of acetic acid with n-butanol and ethanol, transesterification of sunflower oil with methanol, and transesterification of dimethyl oxalate (DMO) with phenol.…”

Syntheses and catalytic activities of new metallodendritic catalysts

“…15 The advantages of the dendrimers are related, among other reasons, to the possibility of combining different chemical species, such as the core, branching and terminal groups. Various dendrimers have been employed in catalytic epoxidation of olefins, for example, S. Chavan et al 16 used benzimidazole-functionalized dendrons as molybdenum supports, J. H. Noh et al 17 employed colloidal Pd and Pt nanoparticles synthesized by dendrimer templates, M. Peng et al 18 synthesized a novel series of PAMAM dendrimer-supported chiral salen Mn(III) complexes, and M. A. Fardjahromi et al 19 synthesized Mn(III) salophen supported on a nanosilica triazine dendrimer.…”
