Epoxidation of Fatty Acid Esters with Aqueous Hydrogen Peroxide in the Presence of Molybdenum Oxide-Tributyltin Chloride on Charcoal Catalyst
Itoi, Yasushi,Inoue, Masami,Enomoto, Saburo

The epoxidation of fatty acid esters was carried out with a 30percent aqueous hydrogen peroxide in the presence of a molybdenum oxide-tributyltin chloride on a charcoal catalyst in 2-propanol at 50 degC.Such inner olefins as ethyl erucate and ethyl oleate gave good yields of 77 and 76percent, respectively.Ethyl elaidate, a trans-form of ethyl oleate, was less reactive (40percent yield).Several vegetable oils such as rapeseed oil, olive oil, soybean oil, cottonseed oil, corn oil, and linseed oil were oxidized with the oxirane oxygen contents of 5.3 to 3.5percent.
Method for regio- and stereoselective synthesis of (E)-Β,γ- unsaturated acids from aldehydes under solvent-free conditions
Zhang, Shi-Jie,Hu, Wei-Xiao
experimental part, p. 3093 - 3100 (2010/12/19)
Synthesis of (E)-β,-γunsaturated acids from aldehydes with malonic acid has been explored under solvent-free conditions. The modified Knoevenagel condensation reaction with N-methyl morpholine (NMM) as catalyst exhibits highly β,-γ regioselectivity and exclusively E-stereoselectivity. A mechanism accounting for both regio- and stereoselectivity has been proposed and preliminarily studied. Copyright Taylor & Francis Group, LLC.
Silica-supported dendrimer-palladium complex-catalyzed selective hydrogenation of dienes to monoolefins

, p. 725 - 731 (2007/10/03)
The selective hydrogenation of cyclic and acyclic dienes to monoolefins occurs under very mild conditions, in the presence of silica-supported PAMAM-Pd complexes. The activity and selectivity of this reaction is sensitive to the dendrimer structure. These dendritic complexes display excellent recycle properties, retaining activity for up to eight recycles.
