dec-2-ene

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of copper (II) chloride dihydrate [10 mmol] and palladium (II) chloride [1.0 mmol] in water [10 ml] was stirred for 10 minutes at room temperature. Then 1-decene [3.51 g, 25 mmol] was added followed by benzene [15 ml] and dodecyltrimethylammonium chloride [2.0 mmol]. Oxygen was bubbled through the solution at 80° C. for 48 hours. After cooling to room temperature, ethyl acetate (15 ml) was added and the solution was filtered. The filtrate was dried using anhydrous magnesium sulphate, and then distilled to provide pure 2-decanone in 75% yield and 2-decene in 2% yield. Oxygen was bubbled through the solution at 80° C. for 48 hours After cooling to room temperature ethyl acetate (15 ml) was added the solution was filtered The filtrate was dried distilled

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: In this example, inverse electron demand D-A reaction of acrolein with 3,4-tetrahydropyran is described. The procedure involves refluxing of 0.056 g of acrolein, 1.68 g of tetrahydropyran and 0.30 g of the catalyst prepared according to example 1 above in 10 ml of benzene at 60 (C 20 h. The catalyst was filtered off. After evaporation of solvent, the residue was chromatographed over silica gel column by eluting with 5% acetone/petroleum ether to give 0.12 g of endo adduct, 1,9-dioxabicyclo[4.4.05,10 ]dec-2-ene prepared C 20 h The catalyst was filtered off After evaporation of solvent the residue was chromatographed over silica gel column by eluting with 5% acetone/petroleum ether
