By adjusting the reaction conditions, different molybdenum loadings of 1.5 and 5.9\u2005wt% were obtained, which correspond to 3% and 14% of the phenylene contents. The texture properties of the materials as well as the nature of the surface\u2010fixed complexes were characterized by powder X\u2010ray diffraction, transmission electron microscopy (TEM), N<jats:sub>2<\/jats:sub> adsorption, FT\u2010IR, UV\u2010vis and MAS (<jats:sup>13<\/jats:sup>C, <jats:sup>29<\/jats:sup>Si) NMR spectroscopy. The derivatized organosilicas were examined as catalyst precursors for the liquid\u2010phase epoxidation of <jats:italic>cis<\/jats:italic>\u2010cyclooctene, 1\u2010octene, <jats:italic>trans<\/jats:italic>\u20102\u2010octene and (<jats:italic>R<\/jats:italic>)\u2010(+)\u2010limonene at 55\u2009\u00b0C, using <jats:italic>tert<\/jats:italic>\u2010butyl hydroperoxide as the oxidant. For each olefin the corresponding epoxide was the only product detected. In the case of cyclooctene, the intrinsic reaction rates per surface molybdenum atom were similar for both Mo loadings (TOF\u223c1150 mol\u2005mol<jats:sub>Mo<\/jats:sub><jats:sup>\u22121<\/jats:sup>\u2005h<jats:sup>\u22121<\/jats:sup>), suggesting that the resultant materials act as single site epoxidation catalysts. Leaching tests and metal analyses of reaction solutions showed that the catalytic activity stemmed from the immobilized species and not from the leaching of active species into solution. The oxidation of limonene gave limonene oxide as the only product in 95% yield at 3\u2005h, which reveals an outstanding regioselectivity to the epoxidation of the endocyclic double bond.<\/jats:p>","DOI":"10.1002\/adsc.201000042","type":"journal-article","created":{"date-parts":[[2010,7,6]],"date-time":"2010-07-06T18:00:00Z","timestamp":1278439200000},"page":"1759-1769","source":"Crossref","is-referenced-by-count":26,"title":["Grafting of Molecularly Ordered Mesoporous Phenylene\u2010Silica with Molybdenum Carbonyl Complexes: Efficient Heterogeneous Catalysts for the Epoxidation of Olefins"],"prefix":"10.1002","volume":"352","author":[{"given":"Ana\u2005C.","family":"Coelho","sequence":"first","affiliation":[]},{"given":"Salete\u2005S.","family":"Balula","sequence":"additional","affiliation":[]},{"given":"Sofia\u2005M.","family":"Bruno","sequence":"additional","affiliation":[]},{"given":"Jo\u00e3o\u2005C.","family":"Alonso","sequence":"additional","affiliation":[]},{"given":"Nicolas","family":"Bion","sequence":"additional","affiliation":[]},{"given":"Paula","family":"Ferreira","sequence":"additional","affiliation":[]},{"given":"Martyn","family":"Pillinger","sequence":"additional","affiliation":[]},{"given":"Anabela\u2005A.","family":"Valente","sequence":"additional","affiliation":[]},{"given":"Jo\u00e3o","family":"Rocha","sequence":"additional","affiliation":[]},{"given":"Isabel\u2005S.","family":"Gon\u00e7alves","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2010,7,15]]},"reference":[{"key":"e_1_2_6_1_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja9916658"},{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1038\/47229"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.1021\/cm9903935"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1039\/b504511h"},{"key":"e_1_2_6_5_2","doi-asserted-by":"publisher","DOI":"10.1002\/ange.200503075"},{"key":"e_1_2_6_5_3","doi-asserted-by":"publisher","DOI":"10.1002\/anie.200503075"},{"key":"e_1_2_6_6_2","doi-asserted-by":"publisher","DOI":"10.1039\/b707388g"},{"key":"e_1_2_6_7_2","doi-asserted-by":"publisher","DOI":"10.1038\/416304a"},{"key":"e_1_2_6_8_2","doi-asserted-by":"publisher","DOI":"10.1039\/b304430k"},{"key":"e_1_2_6_9_2","doi-asserted-by":"publisher","DOI":"10.1021\/cm034898d"},{"key":"e_1_2_6_10_2","doi-asserted-by":"publisher","DOI":"10.1002\/cphc.200700322"},{"key":"e_1_2_6_11_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja0290678"},{"key":"e_1_2_6_12_2","doi-asserted-by":"publisher","DOI":"10.1021\/cm071258s"},{"key":"e_1_2_6_13_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja0453230"},{"key":"e_1_2_6_14_2","doi-asserted-by":"publisher","DOI":"10.1021\/jp055548c"},{"key":"e_1_2_6_15_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja054103z"},{"key":"e_1_2_6_16_2","doi-asserted-by":"publisher","DOI":"10.1021\/cm051935n"},{"key":"e_1_2_6_17_2","doi-asserted-by":"publisher","DOI":"10.1002\/chem.200801238"},{"key":"e_1_2_6_18_2","doi-asserted-by":"publisher","DOI":"10.1246\/bcsj.79.1463"},{"key":"e_1_2_6_19_2","doi-asserted-by":"publisher","DOI":"10.1021\/cm702271v"},{"key":"e_1_2_6_20_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja026799r"},{"key":"e_1_2_6_21_2","doi-asserted-by":"publisher","DOI":"10.1039\/b901600g"},{"key":"e_1_2_6_22_2","doi-asserted-by":"publisher","DOI":"10.1039\/b716141g"},{"key":"e_1_2_6_23_2","doi-asserted-by":"publisher","DOI":"10.1002\/ange.200903985"},{"key":"e_1_2_6_23_3","doi-asserted-by":"publisher","DOI":"10.1002\/anie.200903985"},{"key":"e_1_2_6_24_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja055851r"},{"key":"e_1_2_6_25_2","doi-asserted-by":"publisher","DOI":"10.1021\/ic9004664"},{"key":"e_1_2_6_26_2","first-page":"2221","author":"Kain J.
