Immobilization of MoO2(acac)2 on Multiwall Carbon Nano Tube and Epoxidation of Alkenes
The acidic group (-CO2H) of MultiWall Carbon Nanotube (MWCNT) converted to acyl chloride group (-COCl) producing of MVCNT@COCl. Then the reaction of MVCNT@COCl and MoO2(acac)2 resulted in direct immobilization of the MoO2(acac)2 and the formation of MVCNT@CO(acac)MoO2(acac) catalyst. In addition, the MVCNT@COCl was esterified...
متن کاملCatalytic Epoxidation of Limonene
The epoxidation of limonene with hidrogen peroxide was studied over zeolite Tibeta (a large pore material) and heteropoly acids on carbono and alumina supported. PW11/C was catalyst the best tested. Introduction In the last years, the increase in environmental restrictions lead to the search for new oxydant systems to replace the traditionals in order to avoid the generation of polluting efflue...
متن کاملCatalytic epoxidation of C60 using Mo(O)2(acac)2/(t)BuOOH.
Highly oxygenated fullerenes, C(60)O(n) with 1 ≤ n ≤ 13, have been prepared by the Mo(O)(2)(acac)(2) catalysed oxidation of C(60) with (t)BuOOH. Increasing the catalyst : C(60) ratio or increasing the reaction temperature increases the yield as well shifting the product distribution to higher oxygenated products, in contrast, increasing the (t)BuOOH concentration shifts the product distribution...
متن کاملHeterogenization of Alkene Epoxidation Catalysts
Este trabalho descreve nosso esforço em heterogeneizar catalisadores para epoxidação. Tanto o molibdênio ancorado quanto o engaiolado pelo método de sol-gel mostraram grande seletividade, mas possuem suas atividades fortemente reduzidas. Por outro lado, silicatos de molibdênio foram muito ativos e estáveis até a formação de diols na mistura reacional. Catalisadores heterogeneizados de rênio for...
متن کاملAnomeric Hydroperoxides; Synthesis, Enantioselective Epoxidation
Some time ago we reported the oxidation of 2,3-unsaturated hexopyranosides and 2-Cmethylene glycosides with hydrogen peroxide in the presence of molybdenum trioxide catalyst to give the corresponding anomeric hydroperoxides 1-5. Relatively stable hydroperoxides 1-5 were used for enantioselective oxidation of prochiral alcohols and sulfides in the presence of Ti(OiPr)4 with stereoselectivities v...
