Baeyer–Villiger oxidation of cyclic ketones using Fe containing MCM-48 cubic mesoporous materials

Synthesis, characterization, and photocatalytic activity of MCM-41 and MCM-48 impregnated with CeO2 nanoparticles

“…It can be seen that peak (200) is not strong enough and also that the diffraction peaks move to the high angle, and the peaks become weaker when the CeO 2 particles are doped into MCM-41. The increase of CeO 2 particles in the framework of MCM-41 is due to reduction of the tunnel size of the substrate [9][10][11]. The XRD patterns of MCM-41 and MCM-41/CeO 2 (wide angle) are shown in Figure 1b.…”

“…The solid was dried at 80°C overnight in static air. The dried powder was ground finely and calcined in static air at 550°C to remove the surfactant molecules for 6 h [10].…”

The dual role of micelles as templates and reducing agents for the fabrication of catalytically active hollow silver nanospheres

“…6-methyloxepan-2-one and 4-methyloxepan-2-one) 5 similar to literature reports. 18 Cycloheptanone forms the corresponding lactone at high turn-over number (entry 7). The acyclic methyl ethyl ketones and isobutyl methyl ketone also lead to formation of corresponding ester in very high yields (entries 8 and 9).…”

Aerobic Baeyer–Villiger oxidation of cyclic ketones over periodic mesoporous silica Cu/Fe/Ni/Co-HMS-X

“…2 mmol of substrate (Acros 99.8%) and benzaldehyde (6mmol) were taken in a two neck 50 mL round bottle flask fitted with water condenser. The mixture was heated at 50 o C and molecular oxygen was bubbled into the mixture at a flow rate of 10 mL/min (maintained by Aalborg mass flow controller) for 2h under constant stirring at 540 rpm using Tarson spinot digital magnetic stirrer [14]. GC analysis of the sample was done using a gas chromatograph (CIC-India) fitted with SE-30 column.…”
